Thank you very much Toxxy. I was stuck on this page: https://www.phpbb.com/customise/db/exte ... ensions-86
The problem for me was that the link to get you to the download page - in my case it says "Board Announcement" - isn't obviously a link. It only looks like it might be a link when your mouse hoovers over it. You response inspired me to meander my mouse all over the page once more and luckily happened to run it over the "Board Announcement" text and bingo! it lit up and then I finally realized that it was the link I needed.
So thanks very much. Bob
