User:BilCat/Scripts/rollback.js

• How to use:

*

* Add the following to Special:Mypage/monobook.js as a

* logged-in user using the monobook skin:

* importScript('User:Gracenotes/rollback.js');

*

* On diff pages, history pages and user contribution pages,

* a "sum" link will appear next to "rollback".

* When you click on "sum", you will be prompted to enter a

* summary. Press "Cancel" to cancel, and leave a blank summary

* to use the default. In the summary, the text "$user" will

* automatically be replaced with the user name you're reverting.

* e.g., "rv edits by $user; not true"

*

* To disable the link from appearing on any one of the pages,

* add a line containing a list after the "importScript" statement.

* The options are 'diff', 'history', and 'user'. For example, to

* disable the link on history pages and user contribution pages:

* rollbackLinksDisable = [ 'history', 'user' ]

*

* Please contact if there are any problems :)
