I decided I needed to clean up my e-mail inbox today and went to the last page and found an e-mail from Konstantin Quilter's Board from October 25, 2007. So I lurked/read incognito for over two years before joining on January 17th, 2010.
Am I the only one who did this? I finally joined because I wanted to comment on a posting. It would be interesting to know why you joined too.
