Hi Anne,
The bad news is you will have to insert code manually (following Heather's example above) to achieve a text link which conceals the URL.
When I wrote the FAQ, we did have an extra hyperlink button with user-friendly javascript prompts. Unfortunately, when I upgraded the forum last summer I discovered that the code which Hituro and I used to achieve this wasn't compatible with the newest version of SMF.
I did ask for help at the Simple Machines support forum, but no-one came forward with any suggestions. They get so many requests over there, the techies don't have time to answer everything, and I didn't want to make a nuisance of myself by bumping the topic too many times.

I guess I could try them again...
