well, don't get discouraged. things will look up.
i'm amazed at hearing that any pi phi chapter is having to cob. the pi phi chapter at my school is one of the top sororities.
back to the subject though. i am the queen of cob stuff. my chapter had to cob 24/7. we weren't very successful and ended up closing, but our efforts were huge. here are some helpful ideas for doing cob:
coke dates - great thing to do, sounds like you are already doing something like it by taking girls out for ice cream, etc. that's basically what a coke date is.
we tried to go all out for cob just as we did for formal rush (before we went to a no frills formal rush). do fun theme parties and have ice breaker games that will be fun for the PNM's.
telephone duty - doesn't sound like much fun, but essential. you need to get a list of names from panhellenic that gives the info of girls who dropped out of rush, aren't affiliated, etc. then you just start calling and see if you can invite them to come to an info night or out for a coke date. works well, trust me.
whatever you do, don't get discouraged! stay upbeat and positive or you'll be dead in the water.
keep me updated on how your chapters are doing. i hope to hear you have a bunch of new girls soon.
