Not keen on the look, too small and basic -- looks like it would be awkward to use on a regular basis. The white pages that appear after you've done something like make a post are really.. unattractive. When you modify a post especially you're left with no link forward, and you have to click the back button twice in order to get back to the topic or even a link to the board index.
Functionality wise it has all the necessities but lacks any of the more "miscellaneous" features such as formatting, attachments, notifications(?), etc, etc. You should also perhaps try to think of something unique you can add to your forum that would grab some attention - depending on what kind project this is for you.
The navigation I found is quite bizarre. The forum link (although active) should still be clickable. People will probably more often than not spot that link hoping to take them back to the board index, before the actual 'board index' breadcrumb or the "Forum" link right below it (which seems odd to extend the menu down for just one link), and get frustrated if it isn't actually a link. I also couldn't find the 'modify profile' section easily. I was expecting it to be somewhere within the forum tab, as it's a forum profile, but instead was hidden away in the members page as a barely noticeable link in the top right.
Not a bad effort though, just needs work.
