Thanks for the suggestions. I'm going to ask them for a few days to give them my answer -- that is if they even offer me the job in the first place.
Then if they offer it to me and give me the days to make a decision, I'll contact the other places I've applied and ask about the status of my applications. I'm not really in a position where I can turn down a job, but relocation is expensive and time consuming!
I'm keeping positive though!
