You say the lady was from Shergroup, Richard, but she may not have been. Back on the technical side, it's always worth checking the registration of suspect web sites using whois.net for global or US sites and nominet.org.uk to check UK web sites.. Checking shergroup shows:
the owners of shergroup.co.uk are Shergroup Ltd ... CM77 8YG
the owners of shergroup.com are Shergroup Ltd ... CM77 8YG
whereas the owners of shergroup.net are apparently twocows.com;the true owners may be hiding for some reason, or maybe Twocows bought the domain so they can sell it to Shergroup if they want it.
Hope this helps.
