Thanks, Bob.
I believe we resolved the matter (on the Q & A board).
My guess with regard to cybertrader is that they use the same software you do and it generates the same (or at least a very similar) cookie request. The ones of theirs that I've seen show the source as "ads.cybertrader.com". The similarity in structure led me to believe they were piggybacking over here and showing "www.inverstorshub.com" as the source.
Incidentally, the explanation we arrived at last night also explains the difficulties I had with "preview" and posting private messages. Since I hadn't accepted the server's cookies, I almost certainly timed out. I'm not particularly fast at composing messages. By the time I finished, the server had lost track of me. Hence, the problems.
Even if that explanation is wrong, it sure sounds good.
