How do end users find DomainAgents.com as broker to make an offer on a domain?

[Drunker]

Have had a number of offers on various domains with DomainAgents as the broker middleman...

Do they advertise widely anywhere?
Are they affiliated with any WHOIS search?

I suspect it involves a fair bit of hard work.

It does raise the question of how can we set up a similar site to find end users. Maybe we should have a domain sellers club.
