Hi, Rita,
At FTM.com it's done with a (for lack of a better word) "preset;" click on the icon next to the smiley to see for yourself.
Since UBB.threads has gone thorough two variations of link creation (of which I'm aware), I suppose it's conceivable that there are any number of them, so I suggest that you post the format for the Web site with which you're dealing so we can see it for ourselves.
The example you posted shows the UNIX path to a document, though, and that confuses me... A link is generally to a Web site, not to a doc on your own Mac, or are you running your own server, sharing on a local network, or some-such?
