1. I like the site, especially the background image
2. The copyright link at the bottom shows 20103. On the login page, I would focus the cursor on the username textbox, like gmail does on the login page
4. According to
tools.pingdom.com, the homepage takes about 20 seconds to load everything, which is kinda long. I hear the recommended time is 2 seconds :-)
5. Register your site on Google Webmaster tools; it will give you a wealth of information on the various ways you can improve your site.
6. Also register on Google Analytics, it will help u better understand the traffic to your site
Overall, a nice site
