I think members who constantly one line every thread and bump year old thread, etc should get warnings. Not only is it supremely annoying but it pushes threads down.
The bumping old threads annoys me to no end. I just want to reach through the computer and smack people when they do it. I mean HOW does a person mistakenly drag up a year old thread? It's impossible.. you have to go LOOKING for threads that old. And it used to just be new members with 10 or less posts doing it that didn't understand how forums work but lately it's been people who have been here long enough to know how forums work.
I'm really tempted to write up a thread about Netiquette since some people just don't seem to get it.
