Ok, here's my five cents. Have mood for critics.
—————————————————
First of all it's not clear what is it all about and what it's for.
What the reason to represent the text as a picture and not as plain text? Torn edges makes me think about 8-bit videogames, not about new age technologies.

Misaligned fields, labels, information icons and Join button.

Could you guess what email did I type there? :)

When I see squeezed banners with overlaid non-readable texts made in MS Paint on Win95 with 640x480 VGA monitor, I think about the company budget which didn't made its way to designer.


Really, why join if I already have accounts on FB, LJ, WP, BS etc. for years and can do even more than Groups, Blogs and Events? Attention from who?

Too many different visually-non-compatible fonts doesn't make it look better.

And when it's active, it goes to another font...

...and finally I feel pain in my eyes after a couple seconds...

Want to switch interface language? Try to find grayed out text somewhere down there and click it... So not obvious.

How can I go to another parts of the website from internal pages without going to /index page?

What are you waiting for... This is a question... Why don't you want to put a question sign there... Why there are two exclamation signs... not three... telling me what I have to do...

Conclusion: I guess site is not ready for feedbacks as I only can see three modules and template. Nothing to check really. That's it.
