!!! Mediawiki has been upgraded !!! Slack integration has been disabled for now due to an incompatibility. If you want to testdrive the new skin (Tweeki), make sure your language settings are set to 'en - English' in your preferences!
Slack is a chat application with lots of integrations. We have multiple rooms, including a #random, #general and some specific channels. Since our Slack is using an invitation system, we included a sign-up form: http://brixel.be/slack/ This will post a message to one of the admins, allowing that person to review the access request. Other custom integrations are the MediaWiki-bot, that post all the changes made to this Wiki to the #wiki channel. This integration still has a minor bug, where the URL is not correctly parsed, since we use semantics.
