Cees,

I'm not going to do this again with you. You have been informed many a time before by others. Change your tone and manner and everyone will welcome you. Be arrogant, condescending and assuming and you will be shunned. So called facts, engineering and calculations have nothing to do with it.

For the record I hold two degrees who's central theme are the Navier-Stokes equations. This doesn't preclude me from asking others what their opinion and thoughts are on aerodynamics. But anyone who's opinion is always based on the assumption that they are always correct and others are, if they are lucky, barely waking up to smell the coffee is just not well received. Dialogue is the key to productive communication. What you do is akin to preaching to the uninitiated - repeatedely.

If I'm lucky you wont respond to this with a myriad of references to other posts or threads.

And it is not cool to bring into this exchange (because it is not a conversation) Ralph's excellent PSU build. It has nothing to do with it.

You go ahead and be careful! I'll go and make myself some tea instead and hope not to blow up my house when I put milk in it...

Man, why is it always this way Cees? Just take a breath and put together two clear sentences with your thoughts on the subject if you deem necessary. But take a step back and realize that everything you say is not gospel. Others will be a lot more receptive. If I'm frank, you sound like an interesting person to meet but if I spoke Dutch and you came across the same way you do in English, I'd have to run hard in the opposite direction. We already have to deal with controversy and issues in our own lives. Let's not bring that here to our RCU haven - if you will.

Hopefully end of input it is.

David.
