Fellow Dems, you may have already received, or will soon receive, notification that you have been enrolled as a User at this site, with a designated role (https://codex.wordpress.org/Roles_and_Capabilities):
- Administrator
- Editor
- Author
- Contributor
- Subscriber
Administrators can do pretty much everything; empower or disempower users of whatever stripe; fundamentally change the look and processes of the site; pretty much everything. Editors can edit the content of messages – even of messages not their own. Authors can revise their own content & delete their own content. Contributors can post but not revise. Subscriber is the first rung; anyone who wanders in off the web gets enrolled as a Subscriber, if their Comment is not spam.
