I've used Joomla on quite a few sites - and also Mambo, which a lot of the other Joomla supporters haven't mentioned.Originally Posted by pagetta
Joomla is a spin off from Mambo and the two share a lot of the same attributes, as well as many of the same add-in components and modules. Don't know enough about the politics of the split to comment on it, but having used both a lot feel I can comment on usability.
Personally I prefer to use Mambo, as I find the pages easier to understand when I need to carry out modifications, but that's perhaps familiarity.
In practice, both are good, and the core systems of both can be used to generate compliant sites, provided you setup the templates correctly.
Where the compliance side falls down is usually in the use of third party add-ins - some are good, others less so.
Deployment and setup is very easy, provided you are with a compatible host.
Although there are stacks of free templates out there, I recommend creating your own to meet the meets of your client - most of the free templates are aimed at being all things to all men[women!], and sometimes end up being a bit over cluttered. Starting from scratch is very easy, and I now find it much quicker and easier to do than modifying a free template to suit.
Both Mambo and Joomla have new versions on the stocks and due for imminent release.
