start high......................................................You can always go lower never will be able to get more than your first offer.
Same thing happened to me with a domain I had know idea what to ask for and had only had it 3 months. sent a relply saying to make an offer and that my last offer was $1250. Ended Up at $1400.
Well, honestly gayideas.com will definitely not sell for over $10k. So why not start at $10k (come on, be reasonable.. if you start out with like $25k they might think YOU're not serious) and work your way down.
Was it from someone who signed their email PhD ?
Make sure that if they ask you to get an appraisal after you write back, that you DON'T.
Search "domain appraisal scam" for more info.
