There are three types of editor.
1. Write When someone has write permissions, they can read and create news articles, have articles proofread, and edit or delete their own articles.
2. Publish In addition to writing articles as mentioned under 1., someone with publish permissions can also publish articles, proofread and edit any articles.
3. Manage Anyone allowed to manage the editorial team can do all the things mentioned under 1. and 2. and can also delete articles, arrange the news page, and (as the word suggests) manage the editorial team, by adding or removing editors, for example.
