Has anyone heard of this fraternity?

[Betarulz!]

As someone who has FH, Acacia, Triangle, AGR, AGS and a local AGNu, I can vouch for who is still and who is no longer limiting in their membership.

Farmhouse is no longer agriculturally selective. I believe that their cahpter at Nebraska is widely considered their "flagship" chapter (stealing the lingo from an earlier thread). I believe that they were founded at Missouri though. They are more ag based than the other top houses at Nebraska b/c they are on East campus, which has all the ag majors and classes, but they are definitely broader in scope major wise than the other East Campus fraternities.

Acacia was never limited in their membership as far as major goes. They did have very strong Masonic ties. Supposedly William Jennings Bryan was a member of the Acacia chapter here in Lincoln, but that was more likely some aspect of a Masonic membership as according to Wiki, he didn't move to Lincoln until after attending law school.

Triangle is limited to majors in the sciences, architecture, and engineering, at least they have a strong lean that way. Yes, members are allowed to change their majors.

Alpha Gamma Rho, AFAIK, remains heavily ag based. I believe that is a national thing. On Lincoln's east campus

Alpha Gamma Sigma was ag based, and b/c of their location at Nebraska (across the street from East campus which is almost entirely ag majors) they are primarily ag, but I know they will look at any major.

Alpha Gamma Nu is the only local in the Nebraska-Lincoln Greek Community, and they've been around for over 50 years (yes 50! most people don't even know they are a local they've been around so long). They started as the AgMen house and then morphed to a fraternity. Again another East Campus house so primarily ag, but not limited by it any more as far as I know.
