Quick, I gotta get to bed! Seriously though, I'm not sure if it was a glitch, or maybe "beta" software, or it needed a reboot? I dunno, just when I tried it, it didn't work UNTIL I clicked the link for text only.
Certainly, I am psyched that it works in MR to reply and create posts (and hope that I'm wrong/got a bad test unit, with jacked up software!!)
