honey/dani-- I stand corrected!
I still feel that your legacy is your business only. While some chapters delight in "We got a triple XYZ legacy away from XYZ!" there is a subtle notion that a legacy is going to be partial to her legacy chapter-- regardless of whether that's true or not.
It's easier to change the form than change long-standing mind-sets. Then again, you could leave that section blank and still run the rumor mill. A friend of mine was a chapter legacy (her sister was still active in the chapter) and despite having friends in all the other chapters and coming into recruitment with the notion "I don't want to join my sister's sorority because I want to do something on my own," she was heavily cut in round 1 because of her legacy status and in spite of the protests her friends in other chapters threw up when those chapters moved to cut her. It was a very emotional recruitment for that group. The girl ended up joining ADPi and at prefs told me that even if her sister hadn't been a member, she knew this was home-- so all's well that ends well, I suppose-- but there was such trauma earlier in that week!
