Custom roles are sometimes desired for a variety of reasons.  A good example would be a research site.  The Principal Investigator of the site may want a role with a title like "research assistant".

This makes perfect sense.

So how do we make the custom role?

It's really pretty simple.  Just do the following:

Click on an image to make it bigger.
Working With People - Custom Roles - Navigate to Roles

1. Navigate to Roles

Go to Admin menu > People > Permissions > Roles.

Working With People - Custom Roles - Add Role

2. Enter New Role Name

In the blank field, enter the name of the role that you want.

Click the Add Role button.

Working With People - Custom Roles - Role Created

3. New Role Added

After adding the role, it will join the others in the list above.

Working With People - Custom Roles - Reorder Roles

4. Reorder Role

To reorder the role, just grab it's handle and drag it up to the position you want it to reside at.

And that's really all there is to creating the actual custom role.  To make the role work, though, we need to finish out the process by giving it a set of permissions.
