Noooo. I was asked the exact same thing about two days ago by Simus. I told him when it got 'revived' last time, that I wasn't as 'committed' as Gunbon or Gunjorn or whatever his name was. I don't know how far it'll go this time, but I'm going to concentrate on Nightfall, Among the Stars, and The Hunt. I might think about rejoining if you do.
Also, for the escape from Riften, got anything major planned? Just want to know so I can prepare myself. I don't have much planned for the escape at the moment.
