Hello
I like the colorful boxes of the Kids Zone, Teen Zone ect... but they and the advertising to the right creates the clutter. Maybe direct your viewers to those links with tabs or something like that? Maybe use the same colors for tabs? That would be pretty and cut down on clutter? Also, the "r" is missing in the "register" link in the header.
Also, although I'm not a Muslim, and I do sympathize with the Arab/Israeli conflict, the 'Boycott Israel" box creates a more political agenda tone to your forum and sort of spoils it for me as I would want to come to a Mother's forum for peace not a sad, stressful reminder of a terribly painful conflict. I hope you don't mind me stating this.
