BioWare has listened to the voices of the community and announced today that they have expanded the free 30 days of gameplay promotion to all players who have reached at least reached Legacy level 6 in Star Wars: The Old Republic. Originally, the promotion only included those who had at least one level 50 character.

While it still doesn't include everyone, it is a chance for players with a few low level alts or characters near level 50 to get their hands on a free month of game time. 

To unlock the Legacy system, you will need to have at least one character past Chapter 1. So long as there are alts on the same server, it may be possible to reach Legacy level 6 without getting to level 50.

If you still aren't eligible at the moment, then here is some more good news. Everyone has until April 22 to have either a level 50 or Legacy level 6 before the promotion expires. You can find the complete details here.
