I normally stay logged in (remember me) whether on or offline. Yesterday, when I opened the page, There was a message on the top, asking, because of the slow speed of the site, if members with many posts could shorten their passwords in order to help. This seemed a little odd??? I then, normal practice, opend new posts, and the same message was there. Only then did I notive that I was logged in as "Mike". Huh!
Anyway. I logged off, Mike or whatever, and logged on again and was able to delete (x) the message. Since then I have not see any abnormalities. Was this spam or an attack of some kind? Whatever, as I said, there seems to be no more interference of any kind.
