Please note that most parking companies prohibit linking to parked domains.

For instance, Sedo's rules at:
http://www.sedo.com/about/policy.php...les_parkers_us

state:

Domain owner may not generate traffic to their domain name(s) or clicks on advertising links by any of the following methods: listings on newsgroups or discussion boards (with the exception of "domain for sale" postings), bulk emailing, ICQ postings, or chat room/IRC postings, iframes, zero pixel frames, hitbots, clickbots, spiders, CGI scripts, java-scripts, or any other similar method.
I'm always happy to see people's domains in their signature. However, please note that live links to your parked domains are not permitted and we will be deleting these links.

Thanks for your cooperation!
