On second thought, I'll post my response for everyone.

I don't think it's a major faux pas to ask the initial question privately on Twitter, but you really should have asked him in person first. I would advise any young man pursuing membership in a fraternity to show interest by (in order):

1) Attending the events, especially community service.

2) If there are no public events that you can ascertain (no website, no facebook fan page, no Twitter to follow for events), THEN find a member and ask him if there are any community service projects you can attend.

3) If you have a good personality, the guys will like you and ultimately share with you the information you need. Be mindful that not every organization is like this, so you may need to

4) Take one of the members to the side after a public event, tell them you've been enjoying yourself, and how might one go about pursuing membership.

It needs to be organic. It needs to be two men who are acquainted with each other having a natural conversation about it.

Many undergrads would not mind that you inquired via Twitter. Many would. I would avoid it. But now that the horse has left the barn, try to do as much of what I already said as possible.
