the layout and top banner is very nice but change the body text font to verdana so that it gets smooth up.
the font is not so good the buttons are nice, and the fourm is also nice
Your site designation is very elementary. You have used just too cold colors, black and white. This would lead visitors to tire and to exit. Additionally you have not fitted your site for SEOs.
PRO: The site is very simple and clean. I like. It already has some good content, and looks like more content is being added shortly.
CON: Forum -- i'm anti-forum, unless the traffic supports it.
Con: I'm an algebra teacher. I spend lots of time removing games from TI-83's, because irresponsible decide that they would rather play super bounce out than work on systems of two equations and two variables. Perhaps it would be good to add a disclaimer, or two... (Not responsible for serving your detentions, yada yada).
First off, you should tell me what is a TI-83???
