Hi Hockberg

May I suggest you make a search as there is a mountain of posts on this subject. That would be the quickest way of getting all the info you probably need.

Generally.

If people continually ask questions which have previously been answered so comprehensibly, it is likely that the people who know will get tired of repeatedly writing the same info. However, having read the info available, if anyone has further questions on any subject, then I know there are many well qualified subscribers who will always be ready to help.
