I've added the link to the puzzle you just solved, up at the top of the results. I did the link as plain text, because if I'd used an anchor tag, or similar, then most forum software won't allow you to include it in a post: even at

you need to be a member of the html group to do that.
I thought about using the: {URL="http://sudoffle.ceptimus.co.uk/Sudoffle.php?p=666"}Sudoffle #666{/URL} format, which would work here for all members (and at most forums) but it would look weird in the results pop-up box, and wouldn't work on other social media platforms.
Of course, it's possible to make the pop-up results box have different contents displayed, compared to the contents copied to the clipboard, but I've not done that, for now...
