[AOII Angel]

Sounds like you need to have a whole chapter meeting just about this alum. Nationals cannot make her stay away, but you can instruct you members that this alumna cannot override the rules of the organization just because she is a "founder." They need to understand that any untoward behaviour in the future will be grounds for a standards investigation and that the excuse that this alumna made them do it will not stand. The collegiates have to learn to say no to this woman. She'll never stop as long as she gets attention when she shows up to campus. Don't dance around the subject...be straight forward with your members, then let the alumna know in a formal letter what your chapter has decided about her involvement with the chapter. Also make sure to let her know that you welcome her to any usual events that alumnae are invited to....not to daily chapter life!
