Now, here are some issues:
The moderation seems to have become very strict. TOO strict, in fact. Can't you allow just a little off-topic chat?
A now major bug. I already told you: Sometimes, the shopping banners disappear, the old "New at LEGOShop.com" banner items disappeared, and "Brickset thinks you are in .". Now though, the shopping banners, the eBay banner, and, worst of all, ALL the news disappear! Fix this bug, please!
Set reviews could be a little better.
More responses to suggestions in comments would be nice.
Make a kids forum. :P One that wouldn't need another account, too. :P
Quicker moderation of reviews.
Something that would tell us how to become a "Trusted Reviewer".
Implement the Amazon Bargain Watch pages more quickly. :P
That's all, I think.
