There was a time when many placed a site name in their signature line which appeared in every post in the old TD Forum. No one ever complained. I've never seen anyone banned for simply placing a link. I didn't link that blog not because I thought I would be banned, but because it listed at least 20 people, some who probably didn't know they were mentioned. As it turned out, I was right.
I've never had any blogs, but I think I will start one on pet portraits. Coming soon...
