Hi there!
I personally think the line lengths are waaaaay to long (for example the first lot of bullet text you come to). As a general rule i think there should be 40 characters to a line before the line becomes so long you either get bored, or the eye finds it difficult to find the beginning of the next line. I would suggest splitting the width of the text in two, perhaps a new grid (if you have used one).
There is a mix of serif and sans serif fonts (not sure if that's deliberate?), and the acid green to me is a bit dated, but that could be more personal opinion than anything. I would say however that the white text of the menu bar at the top on the green makes the text a little hard to read.
Finally, there's a LOT of text on there. Personally i would never ever read that much text, i would consider simplifying it somehow so people don't bounce right off the site again after seeing that and thinking "sod this"!
There are a few registered symbols which haven't been super-scripted which is a pet peeve of mine, and then just bits and bobs all over that i would tidy up.
That's just on the home page...:icon_blushing:
