Only reg fee, it's 3 words and an .org which kills it. For example, WeCanEarn.org is availiable (first variant i tried) which is a better domain as it's shorter. Actually your domain is availiable in the .net extension, so your .org is reg fee only if you could find a buyer sorry.
I'm just curious, would you actually pay 20-30 for it when the same domain in the .net extension is availiable for registration for about $5.50 using a Godaddy coupon?
The reason is .org is meainly for not-for-profit organizations and sites. .net is closer to .com and many prodit organizations use it. .org generally says something about your business that .com does not. If I am visting a .org site and they ask me to buy something I generally tend to think what they are selling is going to able to get a tax right off or something.
.org has always been known as a not for profit extention, although now anyone can register this extention. The .net is always worth more than a .org with the same keyword
