 The Contribution Scores extension polls the wiki database to locate contributors with the highest contribution volume.
 The extension is intended to add a fun metric for contributors to see how much they are helping out.
-
---- TEAR HERE ---
-
-This is a modified version of Extension:Contribution Scores, the original source
-code for which can be found here: https://www.mediawiki.org/wiki/Extension:Contribution_Scores
-The rest of this document discussed changes made to this copy of the extension.
-
-This fork developed by Eunakria the config option $wgContribScoreIgnoreMinorEdits,
-which is mutually exclusive with $wgContribScoreUseRoughEditCount.
-
-In addition to providing the aforementioned bug fixes, this fork also fixes two
-other unwanted behaviors exhibited by the original extension:
-
-1. When $wgContribScoreUseRoughEditCount was enabled, the extension would query
-   the user_editcount field of the user table but not actually join on the user
-   table, in the parser function {{#cscore}}. This was presumably never noticed
-   since this parser function is not frequently used.
-
-2. On some databases, there was a potential for integer underflow when
-   subtracting unsigned values in both the parser function and contribution
-   score data. This could occur if $wgContribScoreUseRoughEditCount was enabled
-   and edits went uncounted in user_editcount, and was resolved by clamping the
-   right-hand side preimage of subtraction.
-
-There are probably more bugs I don't know about, both in the original upstream
-code *and* my code! In other words, caveat emptor.
