rushing Sigma Tau, need advice on increasing my chances for getting bid

[33girl]

First off, stop using the word "frat." Some fraternity members consider it to be an offensive term. Some don't, but it's better to err on the side of caution.

As to how they determine who gets a bid, there probably is some sort of voting, but other than that, it's confidential.

If you're attending a third event, I would think they would realize that you would join if you got a bid. Don't ask for votes - it will make you look extremely lame and desperate.
