The forum software keeps periodically switching me out of the message I'm composing and taking me to the home page. I found this very frustrating and thought that I was losing messages. Today I realized that if I use my browser's "back" button, I can return to the message I was composing. I can imagine that you'd get a lot of frustration from people who don't realize that -- and even from people who do! I'm on a Windows Vista machine using Firefox.
