Cumsoda comes up as "related sites" on research so Lee might work with them trading or someting.

Also one thing I noticed is that since 2006 their domain whois has changed many times from being in Australia as "Alan T", to Berlin as "Webmaster", to the Netherlands as "New Ideas", to the Bahamas as "Fairfax International Services", all since 2006.

All email addresses reference other sites of theirs as contact info so it is the same person changing their domain whois to 4 different identities in 4 different countries in a 2 year time span.
