Domain Names for Fun and Investing

After my post about solar energy domain names, I got a post from Simmeon informing me about a site he has for people to buy and sell domains on the topic of solar power and enegy in general. The site is http://www.solardomain.co.uk/. Here is the message he sent me:

"In essence the websites purpose is to serve as a portal for those wishing to Buy and Sell Solar / Energy related domain names.

The Solar Domain Marketplace aims to increase exposure for your domains, by delivering targeted users which in-turn will convert into actual sales. As you know the demand for Solar energy is growing at a rapid rate, soon enough the value of these name will increase in-line with the new technologies that will emerge.

The Solar Domain Market should be used in addition to your normal methods of selling your domains. So for those reasons mentioned coupled with the fact Solar Domainers don't have anything that caters for our niche I have created: www.solardomain.co.uk.

Does this cost money?
-No. You can list as many domains as you like for FREE.

What type of domains can I list?
-Solar / Energy domains only. All extensions are welcome."

I'm going to contact him because I did register on his site but never got a confirmation email and I can't login to start adding domains. I'm sure this is just a startup problem and will be fixed soon. If enough people use his site it could be an important place for people to come for these kinds of domains. I think the industry needs more domain sales sites that offer domains on specific topics like this.
