there's a couple problems making a BBW section.
#1 that means that if a girl submit pics and it's not submitted to the BBW section, I have to play god with her ego and decide if I shove her in the BBW section.... and there's no clear way to say "if a girl weighs X# of pounds she goes in the BBW sectioN" since obviously I can't judge that from a tittie pic. There are girls I would consider a little "thick" and that same girl another guy would say is a BBW and vice versa.
#2 That section would be a magnet for people putting in nasty comments.
#3 This would require programming.
#4 I might do it despite all these reasons
#5 it might not be necessary once (if it's ever done) the new script is done testing cause you girls can moderate your own comments.
