It looks fine except it is hard to tell what it is at first glance. Perhaps put some kind of text under your logo stating what it is such as "Computer Technology Forum"
I see a calender page in your forum.I dont think there is a need for sepearate calender page in your forum.
It impressed me on my first visit.The design and color schemes are awesome and it has a unique template.All the best for your forum and thanks for the effort made.
The color scheme is good and attractive but the status icon looks too large, try to decrease its size..
Its good, but get a logo that shows where its all about cause its kinda hard to figure it out in 1 sec.
The design is nice, very simple , easy to read (maybe the text could be bigger - it's a forum people read a lot) About the ads ... i don't think the google ads on the top first page will bring you a lot ( content pages are better ) on first page will look better a banner. And on content pages it should be throw the comments or at the bottom. That's all , good luck with your forum!
