The latest beta test includes voice testing pretty much across the beta grid. The download is available [url=http://secondlife.com/community/bhear.php:3o7pw1up]here[/url:3o7pw1up].
I'd like to try it out with some other CDS residents and, since the RA isn't meeting this week, I'm free at noon SL time tomorrow Sunday 6 May. Anyone interested in trying it out please meet me near the Welcome Area in Aherne.
