hum, visually, just changing part of the header and the icons from a style to the other are not the maximum you can do... i'm sure you can expand these changes and make yourself a real personal look...

for the content, not that much forums is good, you have a good structure... btw, if you have boys/girls forums, i hope you can give passwords or something, so there is a real difference between the two...

a debate forum seperate from the main discussions, excellent!
