[BillionaireJ]

My name is jay... I'm a freshman, and i wanna attempt to join a fraternity next year when i return as a Sophomore.. i was on twitter one day and talkn to a member of a different fraternity, and we were telling jokes about a Trending Topic. in the process, 2 of the members of the fraternity that i actually want to join began to converse with us, and followed me on twitter. A couple of days ago, i sent a private message to one of the members saying that i was interested in learning more about the organization, but haven't received a response... should i mention the DM to him? or just relax and wait? i dont wanna sound annoying cuz i know that nobody wants to be annoyed, i just want to learn more about it other then what i've researched.
