I really enjoy A2k...but I'm also new.
I will tell you that I agree with Letty re: acknowledging others posts...esp. if they are directed at you. It's the only way that new people can feel accepted and a part of the community.
I know that I have offended a few people, because I can tell that they avoid me...Oh well. I didn't mean to offend...tell someone when you disagree or do not appreciate a comment! You may end up with someone who you feel is ok after all.
From a new person perspective, some of you guys are tough nuts to crack! It's like a clique around here.
