The parking platform was Domainparking.co.uk (Domain Parking International) LLP, which 123-REG / Webfusion later acquired and rebranded as 123-parking.co.uk. In addition to the parking companies mentioned above (e.g., NameDrive; Ed was a good friend too), there was also Streamic (James Dale and Paul Harwood), who remain close friends to this day. Not forgetting my other friends in the States, Ammar Kubba (TrafficZ), DomainSponsor (Lawrence Ng & Fred), and the legend Igal Lichtman (DomainSpa), also known as Mrs Jello, who sadly passed away in 2013. There was also Bodis (Matt Wegryzn), which a person we all know and love, James Tublin, later joined.
It became a pretty busy space, and although 123 ultimately bought the company, prior to the acquisition, NameDrive had expressed interest, and DomainSponsor flew my wife and me out to LA to see if they could better 123’s offer. (Both Andrew Bennett and Jim Davis can confirm this, as they were involved in the acquisition process with Thomas Vollrath at the time.) You can still see loads of old posts and mentions of the platform across the forums (Acorn and NP), along with all the old faces, for example:

You’ll also find old sites and timestamps in the Archive if that helps clarify things too. There’s also a mention back in 2009 on HostSearch:
https://www.hostsearch.com/news/123-reg-drives-revenue-to-dormant-domains.asp Plus to further back up it was all real, you can see the change of hands and name changes of the company here:

I hope this helps clarify, guys.
