I reckon I must have been a 'lurker'
for a good eighteen months before posting.
The reason being I had nothing to contribute, and yes I was a taker if you'll excuse the expression!
Not having any knowledge of the subject before joining the Forum, I now feel I have a basic grasp on the subject, and can contribute every now and again, though I do still post the usual ' Opinions on this'.
Cheers Tony.
