BioWare distributed emails last night inviting players to the Beta Testing Weekend planned for this weekend. If you were invited, you should RSVP as soon as possible - the sooner you respond, the sooner you will gain access to the Star Wars: The Old Republic game testing environment. Keep in mind, this weekend is meant to stress test the servers, so there will be a large influx of players trying to get in and play the game. Remember to be patient and anticipate fairly long queue times - plan your time accordingly. Expect another e-mail before the weekend for the exact time your testing access will begin.
Additionally, the official SWTOR site will undergo routine maintenance from 6:00 PM CST on Tuesday, November 22 until 6:00 AM CST on Wednesday, November 23 instead of the usual Monday night to Tuesday morning schedule. Please keep in mind that you will not be able to RSVP to your invite during the maintenance period, as the website will be unavailable.
