The very first thing which i noticed is that if you are going to competite such big buy and sell forums available then don't use SMF, spend some money and make it VB, because if i visit your forum, then i prefer to go for VB forums, just my thinking, ANy way rest of theme is fine good, loqds faster. Keep woeking over it, and hope that you will get a reputed position, And let me mention i have registered myself, just fo testing....i will try to keep visiting. Regards: Arif
