We have a Trello board, feel free to use it!:
Though I don't think we need to put general "maintenance-y" type things on there like correcting mispellings and whatnot, at some point it becomes burdensome to do meta-work when we could be doing real work.
So I say just put the things that we need to be reminded of doing, like Wikipedia, the blogging, and so on on the Trello board, and then the other stuff just plop it in the editing guy: Editing tips and tricks
Sincerely,
A guy who spent way too much time writing up guides and meta-work on Meta that subsequently is never read by anyone so I just concentrate on doing real work instead of collating lists.
