Hey Joe,Of course your right about the relative magnitude of the type of posts I'm whining about....LOL, I I am sometime my own worst enemy, as I have spent more time complaining and pontificating in this thread, than my time wasted by this initial poster that inspired the post.It just caught me off guard, because their was posts are within the rules, but the intention is not....so just hit a nerve...it's almost as if they are being paid to generate the exact type of posts that stay within the rules, but, with intention of sales/networking, not the pursuit of knowledge....it seems to be a more and more common practice in generaAnyway, I appreciate your posts and thoughtful contribution, it has added value to my time in these forums.Have a great day and best of luck!

RUBs per SqFt is a good practice.
