OK, just to recapitulate:
You
went through informal rush in September 2009 and only visited one house, who did not offer you a bid.
Then you
went through formal rush in January 2010 and got cut by all the chapters, including the "nerdy" one.
I think you'd better hang it up, darlin. This is a small Greek system and everyone knows who you are at this point. If you haven't gotten a bid by now, it's not gonna happen, unless one of the groups loses 3/4 of their members over the summer or something.
