I also posted to the RootsWeb support line and got this message back:
Hi,
"We have contacted Hugh Wallis at the address we have on file for him. If he didn't get this, and if you are in contact with him, please have him email us, and we can get in touch at his correct address.

Thanks everyone - I have found the rootsweb support address and sent them a couple of e-mails now - I'm surprised if they had a non working address on file for me but maybe they had my really really old one instead of just my really old one

I await their reply but, since it is a weekend - and a holiday weekend in the US to boot - it might be a while before they get back to me
