BIG THANK YOU to all for your advice.

Luckily, my sisters were all on a wavelength with me. We were read the e-mail Rushee XYZ sent to our president's personal e-mail account, and apparently this girl is a transfer from community college, and fresh out of being engaged to a controlling fiance.
This gave further support to our initial hunch that she just wanted to be involved in SOMETHING, and that she isn't currently the kind of independent, strong woman with an outside life and group of friends (in addition to the sisters) that we are looking for as a founding sister.
In this e-mail to the prez, she was basically demanding to know 'what we thought of her'. Mme. President will be writing back with a brief "We are not at liberty to discuss our reasons for offering or not offering bids. However, you are more than welcome to rush again in the spring."
Maybe she will come back in the spring as a woman who has 'found' her lost identity after a traumatic break-up (we've all had them). But for right now, we definitely need people that can contribute their unique talents to the organization without a whole lot of pushing or pulling.
Just thought you all might like to know how everything turned out...
33GIRL: you are very right...i didn't want changing our minds on a decision like that to break down the integrity of our vision. And I also felt that we'd be doing her a tremendous disservice by accepting her out of pity, knowing that we'd probably alienate her subconsciously later on.
