Hey Steve, great job setting up this forum. I like the way it looks, very clean and fresh. Also a good selection has been made between area's of interest at the main page of the forum.
The only thing I think could be improved is the amount of messages you see on a standard screen-size, there's quite a lot of dead-space. I mean, could you
- reduce the white-and-blue space between messages as to fit more messages in a single page-view?
- decrease the size of the name + info of a message-poster? They are taking up a lot of space right now but are not really useful in the discussion
- move the last bit of every message that is now this digg/technorati/etc + quote stuff to the side of the message? Most people don't write long messages that take advantage of the width of the screen anyway.
- remove the empty title-line, why include if someone is not using it?
Just tips on fine tuning this forum, the content itself is way up there where you wanted it! It's just increasing the speed of taking it all in that can be improved
Keep up the good work mate!
