ah, that makes sense, I did wonder if it was that. Yes, you don't want a whole list of pinned topics.
This is such a unique article though, I can't see that it is likely to act as an open door for more pinned posts. and maybe you can make room for it by unpinning Kel's post about amazing changes which seems to be about something in particular that was happening then, rather than being of enduring relevance to new posters.
sorry Sam, I know I'm being a bit pushy and I promise I won't ask again - but I do think this site is such a lifesaver and the pinned topics work really well at keeping the necessary information up front.
thanks, Lily
