I would like to see something to keep some category’s topic edits under control.
In my community we have todo/guide category with staff “seal of approval”.
We want to make all topic in this category wiki mode for community to be able to update guides but then we don’t have under control what changes are being made.
Option in category settings to require staff or selected group approval would be much appreciated 
Staff (and tl4) can edit it without making it a wiki.
By community I meant all users other than TL4.
I have no problem with TL4 users (in our case it’s 0,35% of all users) but I want to give ability to contribute for rest of users (TL0, TL1, TL2) but with staff approval for each change that they submit.
Oh. Sorry. I somehow missed that bit. There’s a lot I don’t know, but I think that’s going to be pretty hard to do.
It’s a feature request category so I think it’s proper category for that 
Besides, there is already review queue and post flagging, I think it can be mixed and changed somehow to offer this functionality.
Maybe I can contribute this feature via PR if some of more knowing of Discourse internals tip me at which parts of code I should look at (I’m not a rails regular).
