Thanks for getting the ball rolling, Uroboros!
I keep a presence in the following websites:
http://actionbabecentral.com (forum member)
http://www.superheroinecentral.com/~wizard/ (no forum)
HIPComix or Jpeger's old banners (which link to HIPComix) already are hosted in their advertising link pages.
I don't belong to any Yahoo groups at at the present.
Note: Removed one link because of changes in the management of the website.
