I may know the answer to this question. Not sure if it’s due to
the IP address or based on the computer itself or whatever lah, if
you login to sgforums at computer A, then never logout, but you
login to sgforums at computer B, later when you use computer A, you
will realize that you need to login again. That’s why some of you
find that you have to login again despite you never logout, they
are not totally random affairs. It means either you login to
sgforums from another computer, or someone has login to your
account from another computer. I reserve my observations so take it
at your own judgement. I got this because I uses different
computers to do my work, sometimes side by side.
