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.

Users should be able to post any HTML code in the forums so that users can embed HTML5 games in forum messages, which is extremely useful for game suggestion topics.
