Apart from the DHTML transitions, which I also loath. As a consequence of the former, I can't really comment as the layout is too fractured by the effects to comment on, at this time.

Incidentally, I can't see the sites purpose, 'combat bordem in schools' (sic), being a valid one. A site to combat bullying in schools would be admirable, but boredom!! Or, am I missing the point, is it intended to be used out of school?

Anyhoo, school time boredom is surely a matter for teachers & students (and parents?) to combat together.

BTW:
The chat facility offers no protection to it's users, 'Please obey the net etiquette while chatting: try to be pleasant and polite.' isn't gonna stop the freaks & perverts (who don't even have to register to chat) getting in on the act!!

And to top that, you do not provide any bricks & mortar details RE contact, in fact, no real contact information what so ever. For a site aimed at children I would have thought that to be an essential.

Only MVHO.
