Difference between BGLO and GLOs?

[Vixenradio]

I have seen a lot of people writing that they are members of BGLOs or GLOs. This may be a silly question to ask, but can someone tell me what this stands for and what the difference is between the two? Thanks for your help.

GLO stands for Greek Letter Organization. It can refer to any Greek Letter Organization, however, it is normally used to refer to the traditionally white Greeks (I.e. the NPC and IFC orgs). BGLO stands for Black Greek Letter Organization and refers to the traditionally Black Frats and Soroities (i.e. the Divine Nine)
