Published:
The Published option is relatively self explanatory but I'll cover it any way. Use this to turn the SearchBot "On" and "Off" or "Published" and "Unpublished".

Description:

The description offers you extra information information about the SearchBot. This could include instructions for using the different options, giving an overview of the plugin, or provide support information. In this case, the description offers various useful links, a chance to support Handy PHP with a donation, the script version you are using, and a check to determine if you are using the most current version of the SearchBot.
