Help me find the bugs 'infecting' the website. (It's a contest!)

UPDATE: CONTEST IS NOW OVER! Congratulations to all the winners. I still have extra Gmail invites so just email me if you want one.

I've been working on the PSTV Alumni website but I guess my work was a little sloppy. There are now a bunch of little bugs "infecting" various webpages. Please help me find all of the bugs!

Okay, there are bugs throughout the website, but not those kinds of bugs. We're holding a small contest - the first ever PSTV Alumni contest. I've hidden six different bug graphics (the insect kind of bug) in the website. Find all six bugs and you'll be eligible for a prize. Yes, and actual prize!

THE PRIZE:
(Hey, the prize had to cost me nothing.) You've heard the buzz - everybody wants one, but almost nobody can get one. Now you can get your own [link=http://gmail.google.com/gmail/help/about.html]Gmail[/link] email account before they are made available to the general public. You can get your_name@gmail.com before it's taken up like AOL, Yahoo, Hotmail, MSN, etc. If you haven't heard of Gmail you can click the link for more information.

THE CONTEST:
Go bug hunting. Everytime you find a bug on the PSTV Alumni website, write down what bug you found and where you found it. For the location, you can either write the page it was on (ie. "the home page") or copy and paste the actual URL. After you've collected ALL SIX bugs, send me an email with your results to webmasterATpstvalumniDOTcom (replacing the AT and the DOT). UPDATE: Now instead of a random drawing, the first SIX people who email me the right answers will get Gmail invitations!

P.S. Please let me know if you have any ideas for what we can offer as prizes in possbile future contests. (What may people want to win but wouldn't cost us anything to obtain or send?)
