Tom Sayers article 

Thanks for your response. Sorry about my failure to sign my post. I had in fact discovered how to do it, but forgot.

I'll check carefully on any restrictions on 'own research', but I'm assuming that, once something has been published by a regular royalty-paying publisher, and has been reviewed in national papers and so on, the research will be seen as validated. I will, of course, give references wherever I feel they are necessary.

Thanks again.
