 * I installed this plugin on my dev site for testing, and got the following error
   in my dashboard:
 * `Notice: has_cap was called with an argument that is deprecated since version
   2.0! Usage of user levels by plugins and themes is deprecated. Use roles and 
   capabilities instead.`
 * Please update this plugin to use current functions.
