Joan, thanks for the tip.
It must have been the brackets I had around the ctrl F in my instructions for how to use find. I didn't have any around the HTML. That makes me feel better about ancestry censoring links.
The issue was a little frustrating. Not to mention the error they gave each time it happened was that the "server was having issues try back again later". Not helpful. Well, that clearly wasn't the case as I could post plain text just fine. A more useful error handling response would have been something like "stop using brackets, our server doesn't like it!". ;-)
