This is a great guide and very useful, I have cross posted it to the Hive Affiliates Community to be included in our knowledgebase for newbies and for growing as a content creator.
There is one question I have about the <center></center> element, when posting 3speak videos they wrap the video embed in that, but there is a problem with it since it makes the whole post centered, is there some way to make it work correctly and not just remove that element which I currently do?
