Beta Testing
From Star Wars: The Old Republic Wiki
Beta Status
Currently Bioware has a scheduled beta test, but at this time it is not known if it is currently running. It is known, however, that the testers are not allowed to say anything relating to the beta outside of the "Beta User's Forums".
At this time however it is possible to "opt in" for the eventual SWTOR beta through Bioware's website here
If you are selected for beta, you will receive an e-mail to your assigned e-mail address containing a link to instructions to continue through the beta process. (Link for test information)
There are two screenshots of the beta inviting/starting process from the players so far. The "Beta letter" linked here the undeveloped server-select screen looks like this
