I feel that domain name can go high or low depending on how you develop it. It is a good dark, two vocabulary words that are not too long. Best if you can build upon it and it should sell much better as a complete web forum than a domain name.
I think sticking to a keyword in the name with the topic you will be making would help SEO and the price... Dark is too generalll.....I had say reg fee now unless you develop it...
