Thanks to Debbi, I just found out that MSN is in the process of closing the groups feature. They are suggesting to use Multiply as the new provider and they are providing support for the migration. While I have yet to talk to our manager John Sapp about this and when to phase out MSN, I want to reassure that this group will not be going away!
In the meantime, I would like to hear any comments about Multiply, and other suggestions for group options.
