Here's a tip if you find yourself getting logged out while composing long pm's, posts, or reviews. Open Quick Links -> Who's Online in another tab or window. It gets renewed regularly enough to prevent the EI server from thinking you've gone away. I've been doing this for a while and it mostly works. For reviews, I still edit them in a file and then cut and paste, because those sometimes get lost even when I don't get logged out in the middle. Also I particularly hate losing reviews.
