Integrated Help
Every screen in the CMS can be associated with a help link in the upper right corner of the screen. Reseller-level users can edit these links using the "Help URL" text box found in the bottom left of every screen.
Simply enter a URL in that field, and the help link will use that URL. The link will spawn a popup window measuring approximately 400px x 600px, with minimal browser chrome visible.
Additional settings are available under Admin > Reseller > Help.
