A couple of pointers.
Try not to use sarcasm. When you do it in person others can get it from your tone of voice or other non verbal cues. It's just too easy for someone who doens't know you to take it wrong.
Don't feed the trolls. Compared to most places TT is actually rather troll free. Some people just live for conflict. I just don't participate. By responding in kind, all you accomplish is dragging yourself down the their level. However, sometimes I can't even follow my own advice. Some people are just plain idiots. You can try to enlighten them, but it doesn't always work.
I started posting mostly for two reasons. The first was to get some practice writing. The second was to learn something. There is no surer way to find out what you don't know than to open your mouth.
You might want to give Team TT a try. For a few bucks you can post in a forum where most have a really thick skin and you don't have to edit your posts(like AZZ).
Be extra careful when posting after a few, or more than a few, brewskies.
