Sure that is all well and good BUT test builds should NEVER make it to the PUBLIC face of the update delivery network. OR if it does it MUST BE accompanied with a detailed change log and/or the specific change or bug fix that it is aimed at, that we, the users that are dedicated to helping YOU are getting the imformation that is needed to fully test the aspect that needs to tested. Just delivering random builds WITHOUT the information necessary is akin to taking shooting rats in a pitch dark cellar, you may get the odd rat, but you could also shoot your own foot at the same time. If you want the volunteer Alpha/Beta testers to test properly and not get pissed off with the haphazard, seemingly incompetent and VERY unprofessional way it is currently done, provide the information that we (using we as meaning the users) need to help you. If you do not want to make information about the source code public, then run a CLOSED Alpha/Beta delivery system with a REAL bug tracking system, a seperate login and use a N.D.A. for the users who want to assist.
