What are you waiting for? It's been two years!
Go for it, if it happens you will not regret it.
This is one of the many amazing things I love about Phi Mu. There is a chance to come back. Many organizations do not offer this and I feel that it is a shame (although I respect their rights to what they feel is best) because sometimes life really does get in the way and I have seen many a shining star have to leave for situations beyond their control. Knowing that they may be able to come back has always been a comfort to me.
