I know some people are having problems with responding on a thread and when they hit "Post Now" having what they wrote disappear because they are no longer signed in. I've looked for a automatic log out time but have not been able to find a setting. I am going to bring this to Shrinklady's attention to see if anything can be done.
In the meantime, I know it can be really frustrating and very disappointing to work on writing a really long post and then lose it. So I do have a couple of suggestions you can use to avoid this happening until the problem can be fixed.
Before you hit the "Post Now" button, first press Ctrl-A to select everything in the response window, then press Ctrl-C. That way if your text disappears, you can log in, hit reply again and then do a Ctrl-V to paste the text in.
A more dependable method is to write your respnse in another program such as Wordpad, Notebook or Microsoft Office and copy and paste your response from that program into the response window. That way if anything happens you still have everything you wrote. Hope that helps.
