redwingirl - I would encourage you to contact your Recruitment Consultant for ideas! She can give you information on what other chapters are doing - have you used her as a resource? That's what our Fraternity volunteers are there for!!
Good luck - and let us know if you have any other questions... but your PDC and RC are always a great first step to get ideas.
Also, did you see the replies to your public relations question? Here's the thread in case you need it:
