I had a phone conversation with an college alumni and he told me that the would get back to me with some corporate contacts for a new job. Two weeks after the conversation, I heard nothing so I emailed him. He replied back asking for more time and to check again in a week if he doesn't get back to me.
A week passed and I did exactly that, but got no further responses. It's now been another week since then. I don't want to lose this corporate contact lead but I also don't want to irritate my connection with a weekly status check email.
What should I do? Do I email him one more time? If he doesn't respond then I give up? How should I word my email?
