Anyway, today got an email from someone who is interested in buying or leasing the name.
I'm doing nothing with the domain so wouldn't mind leasing it.
Question 1: How much to charge? I was thinking $600 for the year.
Question 2: Do I need to worry about them getting a trademark or something on the name, or claiming squatters rights after they've used it for a year or two?
I bet that's what your rental partner is planning to do anyway.
