So shall I upgade to ND7 Beta 4...

I run a hosted server out of (well recommended, BTW - good guys!), and run a number of users on this server. We're all domino consultants, etc, so we're more interested in new features, etc.

(I myself have been running ND7 beta 3 test servers for a while with absolutely no problem - amazing considering its still beta code. Very very stable..)

So - should we upgrade this server to ND7 Beta 4 ? Is it that stable ? I know its good - is it *good enough* yet for 40+ users, 10k messages per week, 50+ web sites ?
