I have left the announcements forum visible Trev, which contains instructions. But I haven't made any major change since I hadn't really any intention of leaving the change in place, I was only carrying out an experiment because a couple of people were curious about the number of anonymous guests. I thought the community would be interested to see one of the variants of the board's modus operandi. Unfortunately some people dived in to make a big deal about it, apparently completely misunderstanding exactly what I had done, what the word experiment meant.
Of course if I did decide to leave it thus then I would probably want to indicate on the front page that there was more content. Although if the content is so very off-putting as your informant, and Jon Green apparently find it, then perhaps it better remains hidden?
