I'm so glad you had a great experience with one of our sisters at UWG, it is wonderful to hear! I actually graduated from UWG and am a sister from the Alpha Xi Chapter there. I miss the Chapter so much, I go back every year for recruitment!! They are great girls and have a strong sisterhood.
To get to know the UWG chapter, I suggest looking at their website:

UWG, VSU and GA Southern all have strong Greek systems. As you choose your school to attend, definitely look into the Greek systems (though it shouldn't dictate where you attend) and see what each sorority have to offer.
Lastly, enjoy your senior year to the fullest...participate in everything as this year never comes again!!!
