I've been looking around your forum for a couple of hours now (as a guest), I love the overall concept. I am going to be giving you some feedback on the forum again I do love the fact you've made a custom forum software to use, my feedback is just my own personal opinion and if anything sounds blunt I am sorry lol.
When visiting the site for the first time I found it to be very blend design wise, it also felt a little bit all over the place. For example your navigation bar is aligned left and the rest of the forum seems to be central. I found the colours to be a little overwhelming with the darker blue, then the lighter blue and yellow text for the forum categories.
I'll go into more detail here
The Postbit
For me the postbit seems to be very empty not showing the users total posts and other info you may find there. It took me a few minutes to find who was posting the reply as their name is on a box to the right. You have no badges or userbars for staff as far as I can see.
The Forum Page
Again, its mainly just the colour choice and lack of design for me, you are also displaying the forum categories twice on one page, you could use this space for something else. The yellow text for me isn't very nice on the eyes and could be easily corrected.
The nav bar is cluttered, your navigation isn't centered. Your logo is purple which I'd change to either white or a nice blue.
The Forum Stats
The stats area of the site (bottom of the page) is better but the text big and in your face, I'd suggest making it a little more subtle.
Profiles and Features
The site as far as I can tell doesn't have any user profiles which for me is a huge need on any community board. I find it hard to find any unique features, the site seems very limiting and is just a straight message board which we had in the late 90s.
All that being said, I'm so sorry If I come across negative in any way I just really wanted to give you some honest feedback, I've done a few web designs and I've designed many forum themes and custom softwares, I am not that good with developing the design but I can design, so If you'd like I'm happy to do you a mock up taking my suggestions and feedback on board and show you what you could do with the site.
Best of luck,
Merciless
