I like the main site, it's coming along very nicely. The two issues I noticed right off the bat were that the text goes past the border on the right which looks awful and the links on the left are too small, very hard to read. Apart from that I would say that it just needs a bit of tidying. The forum's set out well I'm just not a fan of the design, personally I hate tiled backgrounds, it's very distracting! Thankfully phpbb forums are very easy to customise so it shouldn't be too much bother to change it. Keep up the good work!
