One of the most important and powerful features in Cymplicity is its ability to control access to content and administrative duties. Cymplicity's group and user modules combine to individual, or group, access to parts of your site. Users can be assigned to groups quickly and easily, so that they now can be come part of a private discussion, see private articles, or download member-only files.

Not only does the group and user module control access to the web site, but it also controls access to Cymplicity's Web administration area. This gives site administrators the power to delegate management of the site to others, with limited powers and access.
