Sure, just take us as you find us. And to steal what someone else said, post in general, if someone wants a good luck, take 5 seconds to give em a good luck.
If some one wants an opinion, post it, if you have something fun, useful, question, informative to say post it.
Oh and if you don't like someone, then just don't talk to them - just like at school, you don't talk to everyone.
