Forum Features, Use, &tc. needs documentation

Understanding that the Roll20 forums are home grown, there should be a "Help" link/pop-out on using the Post New Topic box. How does one paste code? What pseudo-html is supported, markdown, common mark, bbcode, &tc. is supported, if at all? These would be helpful to newbies and the threads that may have contained such help are poorly indexed in search, if at all. That's generally the problem with home-grown platforms. Documentation becomes tribal knowledge and is not easily accessed.

There is a Forum Posting article on the wiki that is not linked off the home page. That is helpful. However, it does not diminish the need for a link off the forums header.
