User:Dcoetzee/Followed users.js

/* Followed users is an English Wikipedia tool on Toolserver that
allows you to keep a list of users that you follow, similar to a
watchlist, and lists the most recent edit by each user. The idea was
conceived by User:Quintucket. It requires you to log in with a
TUSC account before you can use it at:

http://toolserver.org/~dcoetzee/followedusers/

This has many uses, such as keeping an eye on warned users,
collaborating with users in a team, mentoring, following students in a
class, or just for learning from the edits of others. All followed
user lists are public.

This optional Javascript extension adds "Follow user"/"Unfollow user"
options to your toolbox on user/user talk pages and a link to Followed
users to the upper-right. To use it, follow this link to edit your
common.js and add "importScript("User:Dcoetzee/Followed_users.js");"
to the end:
