Hi Alan,
I'm genuinely sorry you feel this way but we all have areas of learning others don't understand and an NG forum is as appropriate a place to air them as any.
For those who don't understand something (or even just don't want to read it), they are free to skip it.
If we *want* to understand but don't then we should ask, ask and ask again - that's an effective way of learning.
But it achieves nothing to criticise posters whose posts we don't properly understand.
It even achieves nothing to criticise those who appear to deliberately obfuscate matters to prevent non-geeks understanding (which criticism *doesn't apply here*).
So just ask!
Take care,
Phil.
