So what do you need to do to start chatting? Just fire up your web browser, point it to Puggable.com and create a chat room for your group. To invite others, all you need to do is share a link. The site will display character stats for your player from the armory (as seen in the above screenshot) for easy viewing by your entire group. And if you wish to select the instance you're running and the boss you're going to fight, Puggable will automagically pull up links for strategies, videos, and loot. No one needs to download or configure software (unless you're playing WoW with people who don't have web browsers... but that would just be silly) and there are no passwords to remember, share, or change. I'm hesitant to say it's fool-proof, but it certainly looks like group communication and organization simplified.
Puggable is presently in closed beta (though if you're interested in testing it, you can sign up on their site) with plans for a more open beta in the next few weeks.
