Hello,
No favicon? Get one! Also, purple isn't a great color for a board IMO, You have a nice set of custom icons 5/5. Also the 'powered by vbulletin' can be removed, put something else or just remove it, not neccessary but would be good. I don't know if you could notice but behind the register, member list and calendar there's something wrong with the image. Although I don't like the purple skin, you need to put it as your default one, since the default vbulletin skin is set. Also, The logo is kinda big, make it smaller and ''more'' professional. The bird looking thing could be your favicon, just a suggestion. Overall, it's a great site with a good start. 7.5/10
