Some stuff I wanna see:
Signature bars that show off your game's stats, eg:
That is an example of what you can do with PHP's GD library, that would win over a lot of people!
Potentially an account system, a way to login, so you can see ALL of your highscores, and also see all the games you've played, however the login system would be tricky... ...if you're making match making, then maybe adding friends would be nice, you could see which servers friends are on, and join them?...
I want to see a list of games that use your system on your site, accessible without logging in! I wanna be able to look at each games stats without logging in!
I might add more suggestions later...
edit: Loving the fail:
You need to add slashes to it, or remove html elements
edit2: Would be nice if it said which account i was logged in with, and i hope you MD5 passwords, otherwise, mine is a creepy password
