2 years ago similar thing happened to me too. Though, not like in your case, I was promoting my own solutions on their web site (should not do that :), so I accepted their decision and never tried to sign up again.

Being an owner of web site myself, I know how sometimes webmasters can become oversensitive and unfair for no reason.

Still, watching your contribution to several VFP forums, I may only feel very sorry for Tek-Tips guys cutting off branches they are sitting on. You are doing great professional job for the community in both technical and social ways. Try not to get upset and have a good weekend.
