I have been working on adding user groups to the site to enhance permission based systems and to allow for grouping of users.
I completed the initial implementation on the admin side which is now complete. The groups can now be used throughout the site as a security and/or permissions measure however, at this point in time there are no active sections utilising this technology. This will primarily be used for permissions on the wiki pages. The wiki pages themselves are a little behind at the moment due to some changes in how things need implementing. I will keep updated as things appear however!
