Technical test thread 2011-forever

I thought I might bump up this thread which goes back to 2011 (it's been bumped before) and was started by the wonderful Tiger

It contains all sorts of useful info on technical problems, handy hints for inserting photos and links and, latterly, the fact that we seem to get 'notifications' that we can't get rid of (I'm up to 6).

If nothing else, another trip down memory lane.
