Hi
I am being given opinions here rather than a standard. The reason I asked was because I tried another validation program before I bought this one. That program flagged up my page for having PDF links and no links to a reader. This is ahy I thought it must be good practise to use a reader link. Now I don't like adobe reader because it is a large footprint and I prefer Foxit but it is not for me to be judge and it makes me just as bad as anyone else to shoehorn a customer to use a specific program. It is their choice. Thus I offer the two links.
I thank everyone for their comments on this but it is becoming for of a banter about Adobe and not what I was discussing.
