Guild isn't dying anytime soon. When it comes down to the basics it's just another message board and the people here post up their replies and responses. All the extras are nice, and they do help to make it a better environment, but it's the community that does make a big difference. That's where I believe we have a strong advantage over many other sites. Mahz may not be here 100% of the time, but he shouldn't have to be if you're here to simply roleplay with your friends. 

As it stands, the best thing for any writing works is to always back it up. Google Docs is a great place, and its free. I think no matter what site or community you become a part of you should always learn to back up your works.
