Generally, I find that if anyone wants to continue the RP, they'd remake it themselves. 

I'd suggest checking the topics and seeing when the last post was and what exactly was said. From there, make a decision on whether you want to relaunch it, contact the other users or just abandon it. If you're been gone for a year, then it's fair to mention that the Guild has decreased greatly in activity, so there's a chance that the people in said RPs may have already left the site.

Either way, best of luck to you. Oh, and welcome back!
