Jonathan,

	This is now my fourth mail on this issue with no action. It is rather
rude to add a few lines at the bottom of a mail without removing the
context. To help you count the lines, and re-inforce the point, I will
manually number them below; please count them out loud with me:

	Notice, not even removing the ML signature.

	And then we have the two lines of content:

> Kevin you are right the current i7's support HTT. It has come back with

	Then I read the content, and do the obligatory google search to see if
in fact what you are saying is reliable and useful (it is worth
researching what you say before saying it right ?). Intel's pages on
their current i5 and i3 processors (eg.
http://www.intel.com/consumer/products/processors/corei5.htm ) strongly
suggests the opposite.

	I'm sorry if this seems harsh; but - I would like a lower noise level;
absent that - we'll move you to moderated posting until things
improve :-)

	Thanks,

		Michael.
