How you can contribute, if you're a:
Tell your server admin to install GameStats.
Install and use GameStats, and post your logfiles on the forums so I can test against them.
If you're a Perl programmer or interested in learning more Perl, drop me a line (firstname.lastname@example.org), and I can give you some ideas. If you've got a patch you want to contribute to GameStats, you can either send it to me directly, or post it in the forums, and I'll get it added.
I'm not a very good graphics guy, so a cool logo, and maybe some web template design would be most welcome.
Evangelist, or you just like it:
If you like GameStats, tell people about it! Post news of our releases on your homepage or in forums, drop a link to us, or just tell your friends :)
