stuckiePORTAL was a Portal front-end for SMF.
It added page support, block support, and tied in to SMF’s member system for permissions and things, borrowing heavily from how YaPP was setup.

It was moderately successful and powered a few sites, and potentially still does.

The successor to this was siteENGiNE.

This should still work on new SMF builds, I haven’t really checked.. the couple of sites that I know still use it have not had any problems when updating, however.. so I assume it’s still working!
