Well, benn, for starters, could you check to see whether "FLAC" appears under audio File Associations in version 12.338, and then report back here? That would be valuable training for future beta-testing, grasshopper.
As for the MC beta test team, I slipped in under the wire a year-and-a-half ago, when MC 12 was just coming out of Alpha. I'm sure that's a decision JRiver has regretted ever since--I'm easily the most useless beta tester ever to darken their door.
I can't imagine that they're taking on anyone new now--MC 12 is fully mature, IMO. I think the best course of action is to be patient and start a positive dialog with JimH. He's the one that's going to choose testers when v.13 gets underway.
And don't forget, it's not about the money. Even though the top-ranked beta-tester make $5,000 a week, we really feel that a job well done is a reward in itself. And the second-tier group, earning $2,000 a week--gosh, what great attitudes they have! Such dedication--where would we be without their efforts! A big hats-off to those soldiers!
Oops, I forgot there's a couple of beta testers who actually aren't getting paid ANYTHING! What a bunch of chumps those guys must be! When will they ever get the message?
