May I draw readers attention once more to my FAQ:
In particular I wish to highlight the first rule on advertising. Despite this very clear rule I continue to be approached by organisations who seek to promote themselves through my blog.
I shall therefore restate my position. I will not advertise anyone for money. The form the money is offered is irrelevant: cash, vouchers etc. If you attempt to, effectively, buy your way onto my blog you will not get an answer and your email address will be flagged a spam.
I hope this abundantly clear.
