It turns out that on one particular computer, when logged in as Cannoli, the browser has saved Dark Cannoli'gar as the posting ID. It should not happen that way, since as Cannoli, my color scheme is the old wotmania blues, while Dark Cannoli'gar has a black color scheme, but I guess the passwords got mixed up or something. I THINK it's all fixed now. But that explains why last night's post was not showing up under "My Threads".
