Not sure what to add to all that's being said in the land of Blighty at the mo. Here's one from DAD at another site:
It concerns this David Martin who's wormed his way into Judy M's confidence. He gets around, does our "Dr." Martin. There's a difference between wanting a slice of the national conversation any which way ... and a nefarious personal agenda. Martin is a classic "reinvent himself" merchant [posts passim]. Be very, very careful with him.
Correct me if I'm wrong but I don't think that Martin is a doctor. AFAIK he deals with patents not patients. And if you check him out you will find that he's associated with some pretty unsavoury organisations. Therefore, although he appears to say the right things, I've thrown him in the same category as Charlie Ward, that is, a BS artist. I mean, take a look at his company logo for a start.
