I mostly use the source editor over the visual editor, but use the latter for referencing and I use ProveIt for citations, as I'm not too good at using the templates.
When creating articles on forums, fansites, or other webpages, remember that Wikipedia has two notability requirements for these types of articles. These requirements are:
The content itself has been the subject of multiple non-trivial published works whose source is independent of the site itself
The website or content has won a well known and independent award
While a particular website need not meet both of these requirements, it should meet at least one of them.
