Block yourself from any website at certain times of the day.This plugin allows you to be more productive, and it doesn't waste your time while doing so.
You can with ease dictate the time you want to be blocked from a website, and even allow yourself in only on weekends so you don't unblock yourself, and "forget" to block yourself again!
Feature suggestions are encouraged, but I will only implement features which makes this plugin simpler to use.
