This is getting confusing. Specially except for developpers, I don't think anyone is crazy enough to install that beta version on a live board.
well vb run it on a live board with many users and its not died on them yet and its unlikely to die has vb dont put code out to its at a point where theres only some little bugs left to iron out.
personaly im just running a test forum, my main forums are still running 3.0.7 and 3.0.6 has im running a gallery off them thats a big part of my sites, so they not be getting updated to the gallerys been ported.
