Supercool,

I think at least some of my hesitation on responding is that it isn't the co-edness that tends to define an organization but rather its focus for lack of a better term. If you are looking for a group that focuses on Music then Delta Omicron may be what you are looking for; if community service then Alpha Phi Omega or Gamma Sigma Sigma; if social and housed then perhaps Alpha Delta Phi Society (which has the co-ed chapters of Alpha Delta Phi).
