How do i make an update on an already existing tab? I've seen people who say they've, "just updated" theirs, and I was wondering how they did it.

I'm a bad UG-er and I don't contribute =(

But go to your tab, maybe from your profile even, and do a GOOD search around for buttons. UG hides them on you...
Thanks, and i just sent Someday By Nickelback Power tab to the site
