[RateU]

Very nice, Techu
I did the similar thing to the Quick Thread in my forum some times ago:

Because MyBB use Prototype, so I tried to create it with prototype.
I just use a very simple code and CSS.
And because I don't use a ready to use script, and I have a very very limited knowledge, so, probably it is not a nice design

I think it is more easier to do this with jQuery.
