Brothers have not texted me at all... What does this mean?

[preewee]

I signed up for rush at Lehigh. The first event was basically visiting fraternity tables and giving info, name phone number email etc. with the promise that we would be contacted about events and such. I gave info yo about 5 (there are 21). It's been four days and I haven't been texted once. I know it's not because the fraternities don't like me, I have not had enough interaction with them for them to have any opinion of me. GPA and other stuff like that isnt a problem either. People who know guys in the houses are being texted though. Is this typical of the rush process? That you only get contacted if you know somebody? Not that i care about this, but im not even looking into houses that are considered "top tier". I don't get it... What's the point of rush if you aren't contacted for events just because you're new to the whole fraternity scene...?
