As far as DG requirements go, you yourself do not need to worry about a sponsor form. We have a delegated sister who finds sponsors for each girl that goes through rush for us. Now, a recommendation is something you would approach other Delta Gammas and ask them to write for you. Recommendations are not required, especially at my small school, but they always help.
I hope that clears that up a little bit. If you have any more questions, don't hesitate to ask.
