International Brotherhood of Rail Riders (http://ibrr.org/forum) is my SMF site. SMF 2.0 RC2, Curve theme. Project Magellan (http://ibrr.org/ProjectMagellan) is my TikiWiki site. Tiki 4.0
TikiWiki (http://info.tikiwiki.org/tiki-index.php) is the largest wiki development ongoing currently on SourceForge.
So, I have several membergroups on SMF and several on Tiki. The groups are obviously named differently. As opposed to SMF, the presenting challenge in Tiki is that as a CMS, Tiki allows for a page-by-page permissions system according to user/membergroup.
To create an authentication system wherein signing into SMF allows for clicking the tab (already in place) and passing the signed in member to automatically log into Tiki.
I would appreciate any feedback on this!
