Recently built a site with Joomla 1,5, first time I've used it for some years. Really impressed with the results, and with the range of add-ons, most of which are very reliable. In fact, thinking of switching my own site from static php/HTML to Joomla.

Was discussing choice of CMS with a designer who now prefers Sitellite as being less-prone to security issues. But, I can only say that on trying Sitellite I found its extensions to be full of annoying bugs. Thus I'd rather go with Joomla.

Question is, though, what's Joomla security like nowadays? Anyone here had a site hacked? Mambo in its heyday used to have dreadful security, it was getting hacked every few weeks. I'm hoping you can tell me that Joomla has moved-on from there, and is no longer so vulnerable.
