Hi,
I stumbled over Tikiwiki late in 2005 when I was looking for an open source Workflow engine that could be inked into a website.
I found Galaxia, which brought with it Tikiwiki!
Up to that point I had been using Mambo CMS to run a couple of sites, however, a new project meant that I would need to go beyond Mambos capabilities.
I am currently working on a web-based traceability application for the seafood industry. This will allow seafood to be tracked from the sea to the supermarket throughout the supply-chain... using Tikiwiki + Galaxia
I will post details of the site as it goes live!
Thanks,
Stuart.
