First of all, OLGA still seems to be working fine. Second of all, as others have pointed out, there are mirrors. And lastly, I think it has become a great shame that so many guitar players rely so heavily on tablature. Maybe if it ever does get closed, it will give people an incentive to start learning more songs by ear! After all, music is all about the ear, and not how to look at numbers on a screen. What's even worse, it's a VERY simplified notation, without timing. I imagine that the large number of people who have know idea how rhythm works is due partially to this.
