Seriously, beta is not really suitable for live boards and is not meant for such. If you are the type that loves to upgrade a great deal, beta in a live environment is for you, if not, then wait it out .
Feh, the only problem I've had to this date is the add a new bbcode thing, and I fixed it..So why not use it? We only have like 5 or 6 active members.
The only reason not to use it is un-resolved bugs and im sure alot will change before gold, if you are willing to deal with that and stay up to date with the beta's and RC's then there is no reason not to use it.
