Using Joomla you soon get into digging in the code of extensions and css files. If you don't mind to get your hands dirty and only need the basic communication inside Joomla out your way, then this extension will be a good choice. There might be better commercial extensions but I recommend this extension to any small time WebDev-nerd. Thank You for this, Mostafa. Since You GPLed Your work anybody can pick it up and polish it to his/her needs and the needed infos can be found in the forum on his website.

We upgrade a small site from Joomla 1.0.15 (without many extensions) to 1.5.14 and were to lazy to copy our content "by foot". This extensions did the job for us. The only catch was a password for the old joomla db containing a Dollar sign ($). The extension didn't like that :). After changing the pw the migration worked flawless. Many thanks to the author.
