non-greek girl seeking enlightenment

[MsDTD]

Ok. So my boyfriend is DTD, and I'm non-greek.
Now that you're caught up, someone enlighten me! Fast!
We've been together for a while, so I'm about as familiar as it gets without actually being a brother. And I was always vaguely familiar with the whole concept of lavaliering...but for Christmas, he lavaliered me (aw), and now I want to know more, i.e. privileges, rules, meaning/history, significance, what it is to "deserve" the lavalier, is it true that I'm virtually "am a brother" now, and anything about the infamous "curse of the lavaliere." (Anyone familiar with the DTD-specific rules, etc. of lavaliering, this is your cue.) And enlightenment from non-delts is definitely welcome, as well!

Thanks in advance, guys,
