Sorry if this has come up; I did have a search and couldn't find out if anyone has already asked this. Hopefully a moderator or other such authority could answer.
There's an account on youtube called "StevenSiroVai1", and although no videos have been posted by the owner, some comments have been made on videos (people doing covers of Steve's music). I hope I'm not being too skeptical in wondering whether this is actually Steve? It certainly seems completely harmless, I just wondered, especially since it does say "Steve Vai here". It's a leeeeetle bit strange if someone's pretending to be him.
If it IS Steve, it's really cool that he's encouraging other players like that - of course it would be just like him to do so
