Customizing the Personal Toolbar
The personal toolbar is located just below the tab row. Buttons can be added or removed using the portal_actions window in the Zope Management Interface. Buttons are also defined in other portal tool windows under the Category of user.
In portal_actions, scroll to the bottom of the window to the Add an Action fields and complete the fields as follows:
Title: name you want to appear on the bar
ID: a short name for plone action
URL: string:$portal_url/ followed by the path to the object
(see other portal_actions for how this should look)
Condition: leave blank
Permission: View
Category: user
Visible: check box
Click on the Add button
Plone comes with "log in" and "join" buttons on the personal tool bar for the anonymous visitor and other buttons for the member who is logged in. These buttons are defined in other portal tool windows.
The "join" button is toggled visible/not visible in the portal_registration window accessed from the ZMI . Simply uncheck the box for visible and click on save.
Text can be added to the personal toolbar by adding text in html to the style sheet located in the ZMI at portal_skiins/plone_templates/global_personalbar. Click on the customize button and add the desired text. [NO FURTHER ADVICE ON HOW TO DO THIS.]
