There was some downtime this evening as I converted Off on a Tangent’s content management system from Mambo to Joomla. Joomla is a fork of the Mambo project which is developed by the same team that had previously developed Mambo. I consider Joomla 1.0 the most legitimate upgrade path from Mambo 4.5.2 (as opposed to the Mambo Foundation/Miro International releases that will continue under the Mambo name).
The upgrade went largely without a hitch, but let me know if you run into anything odd.
My choice to tie Off on a Tangent into Joomla (which will likely become less and less compatible with Mambo as the forks diverge over time) will ensure the widest range of support from the open-source community and third-party developers, most of whom have now abandoned the original Mambo project in favor of Joomla. Continuing with Mambo would have been turning my back on the developers who built this excellent CMS, and would likely have limited future plug-in and add-on compatibility.
