I hate to make a complaint so soon after having gotten here, but I've noticed three times that my posts have disappeared into the ether when I've tried to post and been informed that I needed to log in again after having already logged in to post. I can only assume it's because I am often interrupted, particularly when posting from my university as I am now, and so my posts tend to take longer to write.

Is there some way to remain logged in permanently until I choose to log out?
