Usually, it means that the advisor has gotten very busy or has things going on in their lives that indicates they will be spending limited time here at AA. They may check in from time to time, but do not have the energies to direct to actually "working" here at AA. What alot of folks do not understand is how time consuming keeping up with things here can be..
Anyway, it doesn't mean your favorite people have abandoned the site..just that they cannot spend enormous amounts of time here. The status can also be changed back when the advisor requests it.
