Finding my way through WordPress I had a success in eventually working out that I needed to set up a website email box for my website via my website host provider so that it was available to site users. Once there it was easy to forward to my gmail address. This then enabled a Linked In company page to be set up. A little bit of knowledge goes a long way sometimes.
Mintel (www.mintel.com) when delivering a partial report insisted on registering at their site that the web email was used rather than my gmail. As my webmail is forwarded to my gmail this is not a problem. It is interesting that their software knew that my gmail was different from my webmail as I had not input any business or website details.
Website email addresses therefore are of crucial importance.
