"Sweetheart"s, as in the Sweetheart of Sigma Chi for example, ARE NOT auxillary groups. They are meant to be an award of honor for a young lady, usually greek, and there is usually just one of them awarded at a time. Little sister/little brother/big brother groups, on the other hand, have been banned by the NPC organizations and I believe all NPCs have gone on the record saying that they do not approve of their members participating in those type of groups associated with other greek organizations.
