The LiquidThreads extension is not maintained anymore, we should move away from it. This result in bug like this: T11425 (php warning when searching on techbase)
== New tool ==
Discussion tool are important, so we should find a replacement. Multiple propositions:
* Simple wiki talk page without fancy thread with the [Echo](https://www.mediawiki.org/wiki/Extension:Echo) extension
* Pro: Already existing, integrated with the wiki, ping
* Cons: No ping, no structure
* Matrix/IRC chat:
* pro: easy to chat, ping
* cons: not integrated with the wiki, no 'task' management
* Gitlab:
* pro: task management, ping
* cons: not integrated with the wiki
== Archiving the old content ==
When we are moving to a new tool, we will need to archive the old content. We need to find a solution.
