Hi.
No I'm not a part of a bigger group. However there is a small community on my forum and some of them create their own stories. Here is a list of my websites:
http://dollproject.net
http://dollproject.net/shop
http://perfectbimbo.net
http://cyberspace.pl.hostingasp.pl/inne/DollForum/
There is also a dude called Tristo who pretend to be Dollproject and use my "brand" without my permission.
