I just gave someone the link of the page were I was (on this forum, logged in) and when she used the link she was logged in as me. Only when I logged out she wasn’t logged in as me when using the link. She could also post. Seems like a bug.
Hmm… I hope this does not really happen. If if it does, it’s a privacy/security risk. Hope if this really happens that someone fixes it A.S.A.P.
Was she operating from the same IP as you? Such as, you work together and are at the same office, on the same network (where you have a single point of contact with the internet via a router/server setup).
