If you haven't gotten into Star Wars: The Old Republic yet, this may be your chance. The SWTOR team writes:
we are excited to announce that individuals who did not take part in the first Weekend Pass Free Trial will have another opportunity to live out their very own Star Wars saga, for free, with the second Star Wars: The Old Republic Weekend Pass Free Trial! Participants in the previous Weekend Pass Free Trial and any other free trials are not eligible for this upcoming Weekend Pass Free Trial period.
If you want to get in on the action, the free weekend starts on Thursday 22nd March at 12:01AM CDT or 5:01AM GMT, through until Monday 26th March at 2:00AM CDT or 7:00AM GMT. The same limitations as the first free weekend still apply, level caps and chat exclusions. But, it makes up for it by being FREE.
