John,

Thanks for the (above) advice.

The "copy thread address" is best used when:

a) you use the [Reply] option to the post, instead of the "Quick Reply Box" at the bottom. This is a more powerful dialog with editing tools, including "Post a Link".

b) I find the best way to get the link (to paste) is to open the topic using the "Right Click \ Open in another window" option. This way the link address you want is in the "Explorer Address Bar".
