Rogent,
I think sometimes a PM or conversation on 200 may be taken for unfriendly banter, bragging or ect ect. I think this is mainly because there is zero face to face interaction. Facial expression, body language, and tone are all lost in a PM, text, or even on the BBS. And most of the time the little

doesn't cut it. It could easily taken as sarcasms, although you may not have meant it that way.
Like Soulyss stated, you may want to start with some friendly conversation to ease the tension if there is any.
