Sorry about the wait, had Family related issues. Here is the review.
First Impressions: (4 out of 15)
Honestly, there is nothing here on the first visit that makes me say, "Wow, this is the forum I want to go to for medical advice from other people!" It feels bland. Sure, the image in the header links to it being health related, but it doesn't make me think of a forum to discuss how to tackle pain in general. If you were going for a look that doesn't have blaring features and other stuff, then that theme is fine. Otherwise, it doesn't have that look that will imprint much success from first looks.
You don't even have that much on it right now, so that doesn't help that much.
Site Structure: (7 out of 15)
The structure of the forum itself is good, BUT and this is a big but, you need to include periods in your board descriptions! Also, you need to be less generic with the board descriptions themselves (common, "Discuss chronic pain related issues" in the Chronic Pain board? You can elaborate a little on this).
Design Quality: (7 out of 15)
Design quality wise, it looks rather bland. I expected something more from the forum, than a generic free theme, that the only thing that was "custom" so to say, was the banner. Add more graphics to it, to help people identify more with what the forum is about! For example, if you can find a nice small medical related image, you could use two versions of that image for the old and new images for each board. Also, it might help if you find a new image for the header banner, that could have someone at the doctor's office for pain related issues.
Originality: (12 out of 15)
As far as originality goes, I haven't seen many forums out there that are made to serve people with medical issues, so kudos to you for that idea! Eventually you will need a news board, as that is the only non original thing that I can see that needs to be added at some date in the future.
Overall Mark: (30 out of 60)
If you can change your graphics around to better match your forum genre, that can help. Best bet, find good images that can go with your selected theme. Also, try to add more topics to each board you have, as that will help you out in the long term. Though board descriptions aren't always looked at, it would still be wise to finish the punctuation to them, and possibly make them a little bit more descriptive.
All in all, you have a good idea, but you need to better jump on putting together some final touches, so that it doesn't look like a generic forum on the world wide web.
