This is an excellent example for us noobs on how not to get on everyone's bad side. I'm not sure exactly what was going on in the first post, but the following few responses determine it. Things I've learned from this and other posts:

1. Don't insult, intentionally or not, anyone on the board who's been here longer than you.
2. Until well established, don't say anything that can be seen as sarcastic/demeaning.
3. If you realize you've broken rule #1 or #2, immediately apologize and make nice.

(Hopefully I'm not breaking any of these rules myself right now. )

PS. I also have so far been treated very well and made to feel welcome.
