So today, I had a member, known for years, suddenly posting as another member, known for years. At first I thought they were goofing around. But they assured me something went wrong. One member posted with his windows phone and it showed up as another members posts. That member had posted in the thread. Eventually the actual member came along, changed his password and the other member was back to normal. Is there even any way for this to happen? Session issues? I got two members freaking out, one because the other had total access to his account.
