How to add sites:
For each site to add, you need three types of information.
* Name of the service.
* URL to the share icon for the service.
* URL to the service for adding a link. This link needs to be with template code added in the appropriate places.

Each addes site should be placed on a line of its own. Separate the information fields with the following character: |

To make the URL to the service work properly, you need to add template code to it.
Where you want the URL of the current page to be entered, just write %%URL%% instead.
Where you want the title of the current page to be entered, just write %%TITLE%% instead.

Example:
Digg | http://www.example.com/digg-icon.png | http://digg.com/submit?phase=2&url=%%URL%%&title=%%TITLE%%


Extra information:
If you want more sites to be added by default to this plugin, please send me the information about it.
