Any chance of a points system? Users are given points based on their content in their posts. Points can be given/taken away... the more or less changes their priviledges/roles.
Nah, that just puts a list of people who are thankful for that post. It could probably be modified heavily to make it so that user's "thanks" are stored and certain point values can be defined so that if they get 1000 they move a role. But a remove point option would have to be written in.
it really shouldn't be too hard to add those, i have even downloaded to see any of the code. i have never done anything that involves changing roles but i imagine it is only a couple lines of code.
Jazzman's development of the Thankful People extension came closest, but if anyone manages to work up a way of removing points (moderator only) that'd be cool.
