Find out who's linking you in delicious.com
When installed, the plug-in runs automatically in the background when somebody visits your blog - you don't need to add any tag or edit any template to make it work, just make sure you have visitors ;)
You can view the results of these queries by clicking the new Delicatessen option under the Dashboard header on the top left area of the admin area (i.e. exactly the same place where Akismet places its results link).
Just deactivate the plug-in, and remove its folder from the wp-content/plugins directory. Or click Delete for the same result.
