Has anyone tried it or working on it? I thought it might be nice to share help and hints here because generally these can get insanely hard at some points.
Please use spoiler tags. There is a menu item at the top of the editor that will mark the spoiler or you can use the following code:
[ spoiler ]This is the spoiler test.[ /spoiler ] Remove the spaces between the square brackets and the work spoiler. They are there to prevent the forums from parsing it as a spoiler because the code block tags don't do their job properly.
