Well yes, I must say that is a good idea. I know Martin-Eric Racine is working with a new MiNT-distribution and a site for it, but AFAIK it wasn´t intended to be a regular support site. Please correct me if I am wrong on this one.
Lacking a decent support site is something that makes it harder to attract new users. IMHO that is a pity. The MiNT list seems to be most for developers and very initiated users, so a more general support site would not be bad at all..
