Hi there
As for as I know only Managers can migrate a group from MSN
The best thing you can do if you want to save this group is..
first save everything you want/need from here..
then if Minray cant be found open a new group when all settles down or even start one now in the same name and have Minray as manager if you can get in contact with her.
You then can at least keep it going & direct members from here.
All the best
Ellie
