As you might have noticed the forum has been upgraded now, there are quite a few minor improvements so I won't list them all but I will highlight a few.
The most obvious change is the new editor which supports mobile devices, drag'n'drop for image upload and autosaves drafts of your posts.
I've added a spoiler function (second icon from the right), to customise the name of the button it generates use the bbcode 'spoiler=title' instead of just 'spoiler' which is what the button does.
User tagging is new, using @ and the first few characters of a username should allow you to link people in posts.
There's also a members directory now (link at the top of the page) so you can browse/search to find specific people etc.
Let me know if you have any problems or questions!
