And another thing is, the underground fraternities table in broad daylight with all the other fraternities but they don't have a national HQ or anything. I guess someone created the letters themselves.

Not having a national HQ means that they are either a local or a regional (in the case of this group Beta Upsilon Delta). It doesn't mean that they are underground.

edited to add:

Pref night for fraternities is usually a nice dinner or get together where the members get one last chance to talk to the rushees before voting to hand out bids.
