The itwiki community has some (+7) bots running on Toolforge on a tool called "itwiki" (https://admin.toolforge.org/tool/itwiki) and I would be amazing to have a Phabricator project to track down stuff about these bots.
As author of some of these bots and a maintainer of some others, surely this thing will be useful mainly to me at first, but I hope it will also be useful to others as well.
Feel free to adapt this idea after other tools, but the general concept was simply this:
Visible by: everyone
Editable by: everyone
Joinable by: everyone
