As mostly everyone touched up on whats wrong with your site, I thought I'd add a little more for you to think about. Definitely change that index and dont apologize for anything, just put something in its place. You apologize for your server being down. You apologize for your site being down for maintainance. You can apologize for a lot of things, but not the things you can fix directly, and in a short period of time. If you simply put "Welcome to Maroon Central" and some sort of image to go along with it, I would'nt have cared/noticed you didnt had an intro. Its not even a necessity for your site. So I'd fix that up.
Your actual site look good. Not a bad colour scheme. Not a lot of people can pull off green and brown in the same layout, I think you did a pretty good job of that. The first section I checked out was About. You dont need to display your name 3 times (graphics created by, website created by, games created by...) you already explain you developed the site, we get it, you created all the stuff. Ooh, you're validated by w3c....... then why do you have 14 errors on your main page? (http://validator.w3.org/check?uri=http%3A%2F%2Fwww.skizzers.org%2Fmaroon%2FMain.php). I'm one of those guys that actually checks up on supposedly validated sites.
The 'Link to me' link is dead. I'd imagine that to be an important feature. Forums dead. Updates page looks good. In your credits page, its really not necessary to include notepad, IE and MM Flash. Notepad and IE especially dont deserve credit for anything, ever! In the cartoons section, I think it was already mentioned, you link to stick figures looks like a title. I didnt even notice it until I hovered over it by mistake. Toons link is dead. Login link takes me a white page and I have no idea if I'm still on your site. Incorporate this into your website theme. Exactly like how your Join page is. Btw, on the join page, what exactly do you expect people to put in "Anything else I need to know"? Why is that necessary to register for your site?
The rest of the site seems ok. I should've also mention your mouseover javascript, when you hover a link it shows "Go to the ..... page" at the top menu bar, its kind of redundant. Obviously if I click a menu option, I'll go to that page, I dont need your javascript to re-inforce that. Maybe you can find a better use for the mouseover effect, like telling me what I'll find in that section. You're missing meta description/keywords tags, alt tags for images and I just noticed your css is all over the place. First you reference a .css file, then include a new style below for links and in your code you include more styles within (<a style="text-decoration: none"...) including a repetetive one (style="border-left-style: none; border-left-width:.....). Include ALL of it within your .css file, its so much easier and would've saved you so much time. Definitely a few things for you to work on, but you're off to a promising start.
