That's an excellent idea....I can't speak for all of the chapters, but as for Chi Omega and Delta Tau Delta (my husband's fraternity) there is always a need for advisors, both chapter and housing corporation. I worked as an advisor a few years ago and even got to go to national convention in Phoenix, all expenses paid by the chapter....it was a blast. I ended up quitting due to some "personal philosophy" issues I had with one of the other advisors, but she has since quit too so I am back on the team! Being an advisor is a lot of fun. You can really build a rapport with the girls and it is nice to still have a hand in the future of your chapter. I am an advisor at the same chapter I was an active, so it is particularly special for me.
Please post back and give any updates....I'd love to know if you follow through and rush or join somewhere.
