Mixer to fix our rep.

The sorority I just joined has a "boring" reputation....I'm planning on turning this image around. I have a lot of good ideas for parties I got from this thread. However, I'm not sure how to have mixers any more. My university has registered parties and only 5 fraternities and 5 sororities, so it's kind of impossible for me to think of a way to have a mixer where alcohol is involved.

I hate it, but let's face it, alcohol is the only incentive for the other Greeks to want to get to know us better. I would especially love to have a blacklight party w. and open bar....but I don't know how to do any of this.

(And don't get me wrong, I LOVE my sisters and my sorority! I just wish we did more social events.)
