Normally I click on Pettalk and here I am. Sometime though I am "kicked off." This happened again yesterday. I got on in the morning and -- as usual just leave Pettalk on in one screen as I go about my day -- checking in periodically. In the afternoon -- I had become a guest. Signed off and when I turned things back on this morning I still wasn't signed in. It took me a while to remember how (when you don't do something often these old brain cells don't retain it well.)

Why and is there something I can do to prevent this?
