Hi Veena.K, I did not know your avatar remained on the page... No, I have not signed out specifically, because I had lots of trouble getting signed up in the first place: JA had to do it from her end.
So I don't sign out, but once the program threw me out and I had to sign up all over again, get a new password and all...it may be something about my really old laptop, and can't really upgrade the OS now; lots of websites don't even work on my computer any more.
Umm try to reboot your laptop dear, maybe there's a virus hiding....;(( You see, we browse different websites searching for information, such things are bound to happen Virginia!
