i think this would be a really good suggestion but idk it might be just me, would there be anyway of blocking other members from seeing what you type and what they type? i mean not everyone gets along with everyone and other people start crap with the ppl they don't like so then it ruins the whole thread. you know how on AIM you can block users, i think you should install something like that, it would help minimize arguing and help mantain with the spamming and everything
I understand your suggestion and how AIM can block users. However, a linear thread discussion might not make any sense if posts in the middle were missing. Also, if different users have different block list, then each user could be viewing the same thread which could be about different topics simultaneously.
It might seem worthwhile, but could offer more confusion then help.
I will have to think about this a little more, and how difficult it would be to implement. Another possibility could block all posts by status level. For example, let's say you could instantly hide all "New Member" posts? Just another thought for now.
