Sold a pretty domain name

Yesterday was a lucky day: I sold downloadmetatrader.com

But the buyer contacted my with an offer via whois service, not eBay.
This domain name looks nice for forex websites. I was planning to list it on eBay next week, but its gone now.
However I have two nice domains about metatrader I'll keep for now:

http://metatraderexpertadvisor.com/
http://metatraderexpertadvisor.info/

The park pages suck. Godaddy doesn't know what the websites should be about.
Expert advisors are scripts written in Metatrader script language. You must have some programming skills to develop an expert advisor, but you can find hundreds of them free if you search.
