HTML no more
We will soon drop support to HTML syntax, even though it's still safe to use, but instead, we encourage you to use the Markdown syntax, here's a quick cheat-sheet
Also, as our core forum software, NodeBB, evolves, the composer will be revamped to include a live preview of the text as you're typing, temporarily, you can use this great tool, http://dillinger.io by joemccann to preview your the results.
While writing posts, you can include Emoji emotions, find all of the supported icons and syntax here.
you can also drag and drop images to the composer, and your image will be uploaded to our Imgur account and be displayed inside your post.
