Oh, the perplexing that happens at Perplexus!!     :-)

Scott, I assume you read in the FAQ that you could use some HTML tags here.   While that is true they are few and some of them are only allowed by those of more advanced ranks; formatting difficulties in your own posted problems need to be addressed by scholars just before they are published.

I looked at your HTML in an appropriate editor and saw what you intended.

Copy and paste from Notepad would have been a satisfactory option.  I see that you resorted to using the editor here.

Oh! Another thought. Have you realised that you can actually go back and edit your own comments?
