You could use a PHP fanlisting script! I use enthusiast! It's great! But that's for a collective, if you're just wanting one I suggest phpfanbase. But they've taken the script down, I used that ages ago, I might still have it on my computer. On freesites4kids.com I assume you can have php pages, would they give you a mysql database?
If you wanna do that, I could help set it up for you! Or if you just wanna use a plain old HTML form I could maybe help there too, I don't really use them though, but I wouldn't mind looking it up for you. But right now I have to go, I'm going to see Cheaper by the Dozen 2!!!
Oh! I just looked on my computer! I do still have phpfanbase! It's really simple to use!
