Problem

You need to add an existing author to a weblog.

Solution

Use the author's permissions screen to give them access to a weblog.

Discussion

Movable Type's flexible permissions system not only allows you to assign different roles to an author overall, but also different roles per weblog. Before any permission can be granted, the author must be associated with or added to a specific weblog. After associating an author with a weblog, you can then define roles for them.

To add an author to a weblog, click on Authors in the System Shortcuts, find the author you wish to edit and click on their username. Check the weblog and weblog features you want to grant, then click the Save Changes button.
