Will UH Downtown Deltas be back on the yard?

I am interested in the sorority and I know other ladies are too. But they don't answer questions on their facebook page. They have not crossed a line since Spring 07 and I don't know if any of them are on the "yard". They had events this past spring '11 but its been 4 years and they are not suspended. I kind of just want to go to the main campus and attempt to RUSH with Zeta Sigma. HELP anyone.
