Wow that's crazy. That's sad that some poor decisions led to their closure, but I totally agree with Theta HQ's decision.

So, if a pledge is not yet initiated, could she theoretically repledge Theta if they recolonize in a year or so?

If they have family members or family friends, probably. I sometimes slip up and use "pledge" and "rushees" cause it's just easier than being all "PNM" and all that stuff. Argh.

Yes. She would still have to go through the process where the colony members are chosen by national staff, though, and (IMO) would be scrutinized even more closely than someone who had no prior association with the sorority.

I know for me, even though I had no association with Greek life until my own recruitment, rush and pledge are still used in our culture when people refer to sororities and fraternities. And my chapter has been using "pledge class" for so long that old habits are hard to break...
