I've just finished one of the periodic updates to the software that runs the website, bringing it all up to date with the current versions.
In theory it shouldn't change the way anything works, but if you notice any bugs or strange behaviour, please leave a comment below.
One problem I've noticed is that if I insert a photo into text, the default caption isn't set. Previously the caption was automatically filled in with the photo's filename and the user that uploaded it, but that has stopped working. (You can still add a caption manually.) I'll take a look into that later.
