HTML is not necessarily a part of SEO, or is required to do proper SEO. In your example of adding links to forum posts or sites, there's usually a guide for users on how they can do that as some forums do not use the same codes when adding links to posts. Here in the the Affilorama, the HTML code to add URLs are "[url][/url]". For other forums it can be just "<a></a>"
Also, not a lot of forums or websites allow links on the actual post. They prefer their members to place links to their sites on their forum signatures, so there really is no need for HMTL knowledge there.
Basic HTML knowledge is used more in website building than in any other aspect of affiliate marketing. This is where you will find it extremely valuable to know a spot of HTML.
