Visual editor is an alternative to the source code editor which does not require knowledge of wikitext. It may be especially useful for new users who have not edited before and those who only need to make simple edits. While it is useful for writing text and adding images, manipulation of templates is more difficult. While completely optional, Coasterpedia still recommends that regular editors familiarise themselves with wikitext as creating complex articles, tables and templates is much quicker using the source editor.
