Well, the alternative is to assume that you're an arrogant, self-centred tosser with an ego in totally inverse proportion to the length of the fuse on your temper. <shrug> Your call.

The RFCs are not where anything comes from - they are a deliberately hard-to-understand ueber-technical ueber-concise summary of what's what. They are impossible to understand unless you have the right background - that is, unless you've immersed yourself in that sort of thing, and had a lot of help to understand it while doing so. This is documentation intended to exclude all bar the aristocracy, in true American style. I didn't have the right contacts when I was growing up - the wrong department at the university - so I never learnt. I never had the special advantages needed to be able to deal with RFCs. So like I say, you're being deliberately unhelpful with the intention of winding me up. It's quite deliberately - and you're also lying deliberately in the post that I replied to here. I despise such behaviour. Rowland. -- Remove the animal for email address: rowland.mcdonnell(a)dog.physics.org Sorry - the spam got to me http://www.mag-uk.org http://www.bmf.co.uk UK biker?

Thank you for that - it's such a clear, plain explanation that I think you should save it somewhere for re-use.

Jim <jim(a)magrathea.plus.com> wrote: [snip Jim's usual gratuitous vicious nastiness] Jim, just what is wrong with you? Why is it that you have this morbid compulsion to try to insult me and get a rise out of me when I post here? What kind of sick, sad, lonely life do you lead that you sit there at your keyboard waiting for me to post you can get your jollies from winding me up? - winding up someone with quite nasty mental health problems is pretty shitty behaviour, isn't it? Is that how your mother taught you to behave? Did she teach you to persecute the sick and the vulnerable to get your kicks? What sickness of mind do you suffer from, that causes you to behave in the bizarre way you do? And why don't you try to get some help to deal with this morbid compulsion you suffer from? You're sick in the head, Jim - go get some help with your mental illness, you need it. And btw, it *IS* a lovely day: why not go out and enjoy it, instead of sitting at your keyboard waiting for your next change to sneer at me and belittle me. I mean, what are you like? You're sat there, poised and waiting for my next post to give you an `excuse' to insult me again! Can't you see that you're as ill in the head as I am, Jim? Honestly, Jim, you're as mad as I am. The only difference between us is that I don't deny it, and I *AM* seeking help. You're not admitting that you're ill in the head, and you're not tryign to get your problems solved. You should do, Jim - you shouldn't be suffering from your morbid compulsion to wind me up at the slightest excuse. You've got a problem with your head - go see your doctor, he might be able to get you the help you need, desperately.
