We have our convention every three years (conveniently named Triennial Convention)

We send a delegate from each collegiate chapter, though it does not have to be the president, and usually a back-up. I was the delegate for my chapter at the last Triennial convention, and three others from my chapter went. Its a good thing, too, because I got laryngitis the first day!

Each alumnae chapter may also send a delegate.

All of the national officers (except for the International President) also get a vote.

From what I remember, everything is covered for the delegate's transportation, room and board, and convention fees. In our case, they paid everything for me but nothing for anyone else, but we got such a good deal on mileage that it covered everyone else's expenses, too! Our week in GA ended up costing everyone $14 a piece. That's cheaper than being home, and a hell of a lot more fun!

Our next convention is this summer (this month, maybe!) in Kentucky, but I'm not in a collegiate or alumni chapter, so I won't be going.
