This Wiki has has multiple Homepages because it's for creating new Wikis. A Scratch Wiki Home for each language and a About/Test Scratch Wiki Home for each languages community creating that Wiki. see: FAQ
The Scratch Wiki is a collaboratively-written wiki available for free that provides information about the Scratch programming language, its website, history and phenomena surrounding it. The wiki is supported by the Scratch Team, but is primarily written by Scratchers. The Scratch Wiki is a popular source of information for scripts and tutorials and it continues to grow as Scratchers use it as their primary source of information. This could also include advanced articles for Scratchers around the world to build, share and see.

The old Scratch Wiki logo
On December 6th, 2008, LukeTek created the Scratch Programming Wiki, a normal wiki created solely (meaning without anything or anyone else involved) by himself; the Scratch Team was not involved at all. He handed the wiki (gave admin privileges) over to JuiceyBox, who later handed the wiki to Lucario621. He advertised the wiki in the Miscellaneous forum and many people helped contribute to it. However, the articles were of projects, users and the like. The wiki was cleaned up, but by then people had lost interest. A few people stayed behind though and the wiki steadily grew.
Eventually, the Scratch Team saw the wiki. They liked it and wanted to advertise it on the Scratch Website, but they had some concerns: it had advertisements, it wasn't on a scratch.mit.edu domain and there was no way to tell if a user on the wiki was the same user on Scratch. To solve these problems, andresmh, JSO and Lucario621 created a new Scratch Wiki, hosted on the Scratch servers. All three problems were solved: there were no advertisements, it was on a scratch.mit.edu domain and there was a way to ensure that users on the wiki were the same users on Scratch: Account creation was locked; people would request for an account instead.
If people could freely create accounts, it would be possible to impersonate other users by creating an account with their username. To work around this, Scratchers must request for an account.
To request an account, Scratchers go here and request for an account. You will be asked to comment a verification code on a project. This is simply to make sure that you are who you say you are.
If the administrators create the account (can take up to several days, but it is often shorter), then the user will be told on their profile by an administrator. The user can then log in with the username and password they decided when requesting the account.
Not all accounts are created — administrators and Experienced Wikians review all account requests and MUST decide whether to create the account. Having no projects will dramatically decrease the chance of a user getting a Wiki account, as will not giving a reason or giving an extremely brief reason. One's reason should explain why they think they should get an account, what experience they have and any other information if the user wishes. The reason, the correctness of grammar and spelling in a user's reason and the amount of experience a user has all go into deciding whether an account is created.
Make sure to fully read and understand everything on it before requesting to become a contributor.
Scratch Wikis in other languages
The Scratch Team encourages Scratch communities of other languages to build up their own Scratch Wikis.
If your native language is not English or you are interested in foreign languages, you are invited to found a wiki or contribute in an already existing Scratch Wiki of your native language. Every author of the English Scratch-Wiki is welcomed to help as an "International Scratch Wiki Coach" even without knowing the target-languages, because for motivating, coaching and teaching English works.
The first of these international "sister-projects" were the DACH-Scratch Wiki in the German language that started in February 2012 and has over 520 articles (as of February 2016) and a very active community from Germany, Austria, and Switzerland.
It is separately hosted because the Scratch Team advised the founding Scratchers from Germany to start independently, but it got its layout and some MediaWiki extensions from the original English Scratch Wiki. Though it is not only a translation, many articles in the German wiki have a link to their corresponding articles in the other wikis via the so-called Interwiki feature.
The Indonesian Scratch Wiki (Scratch Indo Wiki) is the third of the international wikis made. The idea for an Indonesian Scratch Wiki was already discussed in 2013, but it did not have enough contributors to be created until 2014.
With help and assistance from the DACH Wiki team, the Indonesian Scratch Wiki was created on September 5th, 2014. Their first article was about backdrops and can be viewed here. Indonesian Scratch Wiki is also known as Indo-Scratch-Wiki (short for Indonesian Scratch Wiki) and Scratch-Indo-Wiki (as related to Indonesian grammar rules whereas the adjectives are after the nouns). The wiki has only 77 articles and a handful of members, but is slowly growing.
The official Scratch account for Scratch-Indo-Wiki can be accessed here. The wiki is located at scratch-indo.info.
