Ignoring users' posts in forums
A feature that would be really nice would be the ability to ignore posts from certain users. (i.e. Maintaining a list of users whose posts you don't want to see).
Reasons for not wanting to see certain users' posts would be:
1. Some users just don't reward points, and I don't want to waste my time helping them.
Hmm, I think that was it. Also, I guess if some users post annoying questions, you might want to ignore them.
Sure, it's not a nice thing to do, but that's how it goes.
