Hey,
Like the others have stated, it's quite a long to time to load.
I think speed is very important for a suggestion site.
You should consider one of the following in my opinion, make the site wider, and spread the content out, or keep the current width, and take some content out?
Why? Well, to me, it just looks rather cluttered.
Maybe it could be the dark creame colour? giving me the impression that it's cluttered, or maybe all the forms.
I think you should try to add more colour in where possible, something bright, to freshen it up, not too much though, just bits, here and there, headings, parts to seperate up the content, stop it looking more cluttered and crammed up.
Overal, nice design and idea, just make it less cluttered.
