How do I use HTML in Novel Games forums?

I tried to use HTML here: http://www.novelgames.com/en/forums/bug-in-chinese-checkers.889

However, it didn't get parsed correctly. Maybe this forum uses BBCode instead, or am I missing something?

You actually cannot post HTML code

Then how do you upload images like here? http://www.novelgames.com/en/forums/.815

This thread was posted by us, so we can add images. We do have a plan to support images, videos, rich text etc in our forums. But we are currently busy with other projects and this will come later.
