One of the few pieces of code that I can claim any credit for is the ability to define a database prefix to all the tables in your site and this dates back to the early days of Mambo around the end of 2003. The reason it was frst introduced was to allow site owners to install multiple version of Mambo on a single mysql database.

Everyday a new warez site pops up on my google alert offering me the latest and greatest Joomla extensions and templates. I am not a developer but I talk to several every day and each time the conversation turns round to how to stop rapidshare, megaupload etc. or which method of encrpytion to use.
