Another thought...maybe I just like the anonymity of the forum because I'm kinda a shy person.
For example, one of my distant friends PMd me through eBay because she figured out my username and what I was selling and asked my 100 questions and I felt violated somehow (of course, other friends know me on eBay and we share selling/buying stories all the time - but this was a distant friend).
I think I'd rather just be oblivious to whether or not my SA knows me on the forum, rather than me know that they know who I am and then I have to watch what I post - KWIM?
Great question!!
Frenchiefan, my sentiments EXACTLY.
