That's a way of putting it I suppose, LOL. I'm sure there is a wealth of knowledge on here about it, and I bring some knowledge to the subject myself, I'm just saying the published rules are not clear. If you look back through my comments, rather than a need to say it cannot be claimed, can I suggest the language I use reveals a hope that it can be but also a desire for clarity. It's the easiest thing in the world to say "I know" but unless such statments are backed up with clear evidence, then I tend to discount things. No offence to you, and I'm certainly not saying you have done this, but in general forums can be a haven for people stretching the boundaries of their actual knowledge.
