Cards can relate to each other in several different ways. In the text of any card you can easily make links to other cards (as with any wiki). You can also plus one card to another — to add an attribute, create a section, etc. (this is part of how Wagn is like a database). You can even include the entire content of one card in another, and create formatting that applies to different cardtypes.
Anyone can browse around in and read a Wagn, but by default only users who are logged in to their account can make changes and create new content. Wagn's permissions system lets administrators define roles with additional abilities beyond basic editing and creating relationships, and assign one or more roles to each account.
