In case anyone is interested in checking it out, there is a pretty much open beta happening for the Elder Scrolls Online this weekend & all you have to do to get in is go to curse & sign up for it. Seems as though they are trying to stress test their systems. I'll probably be on a bit over the weekend if anyone wants to try some group content.
Let us know what you think of it!
Seems that you have to be a Curse Premium subscriber to get a key.
I think you just need to have an account, I don't believe you have to be a paid subscriber. I don't have a premium account & it gave me a key. You can use it if you'd like, I was part of an earlier beta so I don't need it.
