@Graham, @notsofast. I now know that I am wrong and you where right. Sorry about the fud remark and thanks for providing thanks proof.
Now everyone, please don't be mad and still have fun mining.
Fair enough, that's a mature response to a critique. People round here are likely to be quite tolerant if all the facts are laid out on the table.
My original post was prefaced traps for the unwary and indeed, the incorrect statement about limits and rewards arises not from malice but from inexperience, which is forgiveable.
Cheers
Graham
