Hi Attom, I think a website dedicated to fake smurfs is a great idea. You probably have one of the largest collection of fakes around and to be able to use it as a reference and have your knowledge of fakes available would be wonderful. The more smurf websites around the better but to focus on such an important part of the hobby in detail on a site is fantastic.
Although Ösi-Schlumpf's Homepage focuses on fakes, he concentrates mainly on repaints and creative smurfs being sold on Ebay, I don't think there is any site that specifically looks at collecting fakes and fake smurfs that have been sold over the years. Please do it.
If you want any help, give me a shout.
Regarding a forum, if you have the right type of hosting, setting up a forum is relatively straight forward. It takes a while to customise it to make it look pretty and set up the features like posting pics but the basic thing can be done pretty quickly. Again, if you want any advice or help PM me or email. A forum specialising in fake smurfs might be a fab idea.
ps. Dyar, you are right, sorry I have been a bit busy the last day or two, guess what I have been doing? Yep, setting up a forum for someone.
