I think the "Hi. Something went wrong if your reading this. Good luck." message is a Mudcat message. I've come across it before, I think when I went to a Mudcat page that wasn't working. I remember being bothered by the spelling of "your," and being bothered because I was unable to change it.
As I recall, I had logged out, but had another Mudcat window open. When I clicked the "you have 3768 messages link," I think I got the misspelled message in question. Well, I checked that theory just now and not being logged in wasn't what led me there - but I got the same Mudcat page more than once, and my guess it that it's legit. If anyone comes across it, let me know.
