MassCategorization

MassCategorization provides a link to a modal (without changing location) which allows the user to list pages to be categorized, via API. It categorizes one page every second in order to prevent overwhelming of the servers.

Usage
In order to categorize multiple pages, add the page names (not page URLs) each on a new line (including their namespace if necessary) and proceed to categorize them. The script will stop when it reaches an empty line; it can be terminated early by blanking the list of pages remaining to be categorized.

The script will not categorize pages that already contain the category that's being added. However currently the script will categorize non-existing pages - this will hopefully be patched in a later update.

It is strongly recommended that you are using an account that has a bot flag, as excessive categorization can flood the recent changes/wiki activity and is often frowned upon.

Monobook
The option to use the Mass Categorization script will appear in your toolbox on the left.

Oasis
The option to use the Mass Categorization script will appear under your "My Tools" list (the toolbar at the bottom of your screen).

'''Please note you must not have the toolbar at the bottom hidden or the script will not function. If you do not see the "My Tools" (or other language equivalent), try clicking Customize and then "reset defaults" to not hide the "My Tools".'''
