I would definitely encourage you to keep up with Alpha Phi's colonization. As a new colony coming to FSU they will certainly be looking for a bounty of upperclassmen to help lead the new chapter. From the sound of this thread it seems like you have great spirit and passion for sorority life and if you go through the process I'm sure Alpha Phi's nationals will see that when they interview you, if you so choose to go through with trying to be a founding member. In addition to your enthusiasm, keep those grades up and get involved in other campus activies to boost your resume for next time. You'll only be more prepared!
I'm really sorry things didn't work out this recruitment but keep your chin up and look forward to the future. FSU is a great school! My sister and brother-in-law are both starting their MBA programs their this fall, so I sort of feel a new attachment for rooting for this school!
