Joomla 1.6 is phenomenal in ACL and tons of other feature .Joomla 1.6 module development is little tedious caz of lack of documentation After a little googling i m going to write my own hack to write joomla 1.6 module development . Joomla 1.6 module development is pretty much similar (PHP side) as per in joomla 1.5 but quite changes in the XML side.
