This is a script that will stop a certain user from appearing in your watchlist page. This script can only mute one user. If you want to mute multiple users, or need help with this script, then ask Panamitsu and he'll be happy to help!
Installation
editOpen your common.js and add the following script:
mw.loader.load('/w/index.php?title=User:Panamitsu/script/Watchlist User Mute.js&action=raw&ctype=text/javascript&username=ENTER_USERNAME_HERE'); // Mute a certain user from watchlist. Backlink: [[User:Panamitsu/script/Watchlist User Mute.js]]
Replace "ENTER_USERNAME_HERE" with the username of the editor you want to mute.
If you need help with installation, make sure to ask Panamitsu and he'll gladly help you!
Usage
editOnce you have installed the script and entered the username of the user you want to block, you've finished everything! Now when you open your watchlist, you will not see that editor.
