Can’t make it to one of the Towers of Midnight tour stops? On his last day on tour for Towers of Midnight, Brandon Sanderson (@brandonsandrson) will be stopping by Twitter for an hour at 1:30 PM EST to discuss all things #WoT, #TofM, #WoK, and maybe even #aMoL!

Join Brandon and the rest of us by following the #portalstone hashtag…but be forewarned if you haven’t read, spoilers may be discussed!

There will also be another member of “Team Jordan” on-hand: the cagey Maria Simons(@MariaLSimons), Robert Jordan’s literary assistant for 12 years, whose famed poker face could face a sore testing in the twitterverse. Special guests @Theoryland (Matt Hatch of Theoryland.com), @zemaille (Linda Taglieri of the 13th Depository WoT blog), @portalstones (Steve Godecke of Portalstones.com), and perhaps even @dragonmount (if someone can drag Jason and Jennifer from their day jobs) will also join in. So brush up those theories and watch out for RAFO cards, I hear Brandon’s getting quite the throwing arm…

If you’re new to Twitter and would like join in, Twitter 101 does a nice job explaining the basics. After you sign-up, search or click the #portalstone hashtag to follow along. To direct a question or comment, mention the specific user(s) by username, preceded by the @sign. If you have any questions or problems, folks from Tor (@torbooks), as well as Tor.com (@tordotcom) will be on hand to help.

Update: The Wheel of Time team has left the tweet-up but we’ve assembled their answers to your questions here. Check out the hashtag on Twitter, as well, as Tor Books is currently hosting contests on it!
