Okay, I have several.
1. These forums are buried in the menu. No problem for techies or for those who browse the web a lot, but newbies might not be able to locate them. A huge button on the homepage would do well to bring more people to the community. Notice the homepages of Opera or Firefox. They've removed all content from the homepage except for a HUGE button saying "Download Now". That helps people who don't know much about computers.
2. Sessions don't work across all parts of the site. For example, when I log on to the forums and try to visit My Logic, my status is "Logged Out". I have to login separately to the forums and the main AL website.
3. The forum's upload file dialog doesn't seem to work in Firefox under OSX. The textbox remains empty even when I've selected a file for uploading.
I can think of only these points now. Will post some more later. This site is a great piece of work
(BTW, I would be glad to help with the site in any way possible.)
