or maybe I'll just avoid certain topics and people...kinda like I do in real life
Yup and really it's not hard to do. Sometimes I'm reading a thread and come across someone I just can't tolerate and I fast forward through it unitl I get past it. The best thing about this discussion board, you can ignore what and who you want. Make faces at stupid stuff and not even hurt any feelings. Chime in and say a word or two, or just read and move on to the next one.
The one thing I find helpful is sometimes I don't post on a thread but I will send a PM to that person if I think what I have to say may make a difference.
