Ian Manley is the person that is the domain holder, until feb 2013.
I seem to recall that there was a member called 'Admin' who set up some of the initial boards, like the wireless message board etc. Mike referred to him as Ian, there was also a letter from Jeremy to Mike asking him to close the forum down where Jeremy mentioned Ian.
The forum used to be registered to GDS, before Mike took it over towards the end of 2010.
