Was just browsing d2jsp and saw this topic (

The content of the guide is pretty good and should be mandatory for new users.
However it's pretty hard to read, since there is a lot of color without real meaning. And well with a dark theme (d2jsp Dark Chrome) the post is almost unreadable because of colors, and inconsistency in titles sizes :
Now with markdown, the same message could looks like :
Which seems a lot clearer to me (the reader) and would still allow the creator of the content to do as he/she whishes since there are a lot of WYSIWYG markdown editors out there.
So my proposal would be to allow user to choose which formats they want (BBcode or Markdown), BBcode being the default since it's what being used as of now
