While going through this forum today, I found that even though I was signed in on one computer (the one i'm using) certain other computers who also were browsing this forum, showed that i was logged in from there.

Also, in between, my computer showed that another user was logged in. I logged out and then it showed that I was logged in (without logging in for the second time).

I would like to know why this happpened. Is it because we are on the same network? It should be corrected because someone can misuse it and send messages from another user's id.
