I think it is OK. I have a link to my website as part of my signature.

I think the rule against other websites is against so called "competing" websites. Sometimes in forums people from other forums will come and post links to their forum... that is usually considered rude in web etiquette. Anything that promotes healing and understanding to the members here should be OK, and I think that includes things that show the personalities of our members here.

If I am wrong about this, one of the mods will chime in I'm sure...
