Fourth Forum
This forum was implemented on June 6, 2012. Due to many problems with the old Vbulletin forum and for security sake, Tigrounette coded this new forum. All the threads that were in the Vbulletin forum were lost.
Note: This 'new' forum has a very similar appearence to the old first forum.
 VBulletin Forum (Third Forum)
The forum changed of source, choosing Vbulletin. This forum was implemented arround May, 2011. Due to problems (the forum was infected by a virus) the forum closed in April/May, 2012.
 Second Forum
A new forum was implemented into the game on September 22, 2010, but as a separate website on forum.transformice.com. On the new forum, you do not have to make a new account; you can sign in with your Transformice one. It's source was phpBB, it was not secure at all, so Tigrounette decided to change the source to Vbulletin.
 First ForumTransformice, allowing players to communicate with each other within a simple message board. It consists of 2 parts: the thread list on the left, and when a thread is clicked, it's contents are displayed on the right side, with an area for posts and comments. The forum is relatively simple, and has been a feature of the FR server since May 22, 2010. It is currently not available on other servers, with the button removed from the menu. The forum is entirely French, so it isn't recommended to go to it if you don't speak the language.
You are unable to see the game while using the forum. You may make someone angry if you appear to be away if you get to a level where partners are necessities, or if you're the only shaman. You can either take quick glances towards the forum, or you can go into your own room to view it without disturbing the game for others.
 Non-French Forums
It is possible to access the other servers' (en, en2, ru, kr) forums through hacking, although the game does not officially support it. The other forums automatically mirror the French forums until a post has been made specifically on that forum, at which point it will desynchronize, but only for that server, and the forums will become outdated compared to the French server. An important thing to note is that all the posts that are not originally from the French will become erased when the game is updated, and will resynchronize with the French forum again.
