It's the steeler's version of
this page. And believe it or not, I think they're even more fanatical over there. (Steel is such a cool but crazy instrument that the folks who learn how to play it share a bizarre bond.)
Also, I know from previous posts that there are some guys here who know a good thing or two about steel also. But until they chime in, ask your questions over at the SGF. You'll learn way more than you ever wanted to know. ;-) CS
