I always liked this blue color
as for forum; the skin is good, while registering it asks additional information, maybe you can add there another box called "Your Mobile Phone Brand/Model", and i hope spammers will leave your forum alone

as for blog; there is no direct link to symbianism.net back(if there is, i couldn't notice). Maybe you can add there a Forum link on the header. I don't know if you wanted forum and blog to be different colors, but it is not bothersome. It separates them.

good luck with the website
