How do you post new riffs...

I'm new to this site and I was wondering if it is possible to post new tabs and riffs on the site. If it is could somebody tell me how to do that.

Thanks,
I.

on the front page click where it says contribute next to the GT logo. you need to have an mp3 for your tab, though, not just a tab by itself. if you just have a tab by itself, put in on guitartabs.cc, that is a great site.
