Starbucks Community Service

Hi out there.

Question, does anyone know why when half of the partners I search for who happen to be "my friends" don't appear?  Is it related to why I can't "invite" them to events as well?  Is this a techincal issue or did they mess up something when setting up their profile?  If so can we help them fix it?  I would love to just type in their names and they pop up or invite them to events and it not show up as an error...

Thanks.
