Mods, I know running a message board is tricky and largely governed by the software you choose, but it seems to me a lot of the recent issues could be solved by having an "ignore user" function.
That way, if I didn't want to read comments from certain folks, I could simply choose to ignore any posts they make. So unless someone quotes them, I'd never even see their post.
That would make me really happy.
Get a life
