Thank you Tim for some insight into the questions I asked.



I though that this being a "public" newsgroup I would be able to post a
seemingly innocent question without being blown away by some
incomprehensible babble on my inconsequential misplacement of a comma.



I admit my post was made in some haste; I am excited about a new project I
hope to start soon therefore did not have the foresight to gather the Oxford
English dictionary and Roget's thesaurus and ready myself properly for the
almighty task of putting together a request on an internet newsgroup.



So am I to gather from Mr Jerry Avins' comments that I am in fact not
welcome here? Is this some sort of clique that only seasoned professional
electronic engineers with an exquisite command of the English language can
attend and pass comment and judgment upon the naive wanderer who may
actually just only require some gentle advice? A prod or push in the right
direction so to speak?



If my question was not an acceptable one please someone point out why? I was
under the impression if you were polite enough and I have no reason to
suspect my post was not, some advice could be asked of the high and mighty
knowledgeable of the internet brethren.



Anyway it's now approaching 3AM in London, so I must close this case. I
apologise for any inconvenience caused as only a misplaced comma can.



AL.
