Mumble is, by far, my favorite client and service for voice in game play. If there's a Pathfinder or Starfinder, with voice on a mumble server, and dice rolling happening on rolz.org or an irc server, I'd love to learn of it! For players who are bline (myself included), mumble and irc would be a nearly-ideal setup! My PFS experience has all been in person at game stores. This is great, but, getting an online fix would be a nice addition.
