Joomla 1.5 ACL explained

Despite claims to the contrary Joomla 1.5 does have an ACL system. It may be rudimentary but when fully understood can be very useful.

To help you I've created a simple table with an overview of who can do what.

NOTE to the accessibility mafia - yes its a table. This is an example of the correct use of a table as it is presenting tabular data. In addition the table has been created with header and id attributes to aid screen readers.
