Hello Maestro,
The following happens while located on a Magnum region. I IM with several viewer users (not friends) over the course of a day from my home on a Magnum region. Each post by *me* in a IM is followed by "Second Life: User not online - message will be stored and delivered later." The person I am IMing with does not see this (unless they are located on a Magnum region as well).
This does not happen on SL and BlueSteel servers, nor LeTigre.
I do not hide my online status in any way.
Thank you.
