rename extension-- that's 2 -- the first guy disappeared on me

For possible legal reasons I need a rewrite on an open source Mediawiki extension called WikiTweet. I need all references & coding changed that references Tweeting. Rename the extension WikiYell and instead of tweeting call it Send a Yell and call private messages a whisper. Here's the original extension page from Mediawiki: [login to view URL]:WikiTweet. Made sure to include accreditation to the original extension in the rewrite. Additionally it needs to work on Mediawiki version 1.19.1 -- I keep getting the following error undefined index [login to view URL] on line 289. That needs to be fixed. Also my system keeps sending me the following warning when I first start the software: no such file or directory in htdocs/includes/ [login to view URL] on line 455 which references WikiTweet.il8n.magic.php. Need all this cleaned up so it works without errors. Other details: PHP 5.3.13 & MySQL 5.5.21-log. Some other issues need to be fixed, but i'll go over those with whomever is chosen. Currently the git download from the Mediawiki's extension's page isn't working so you need to download the files from here:[login to view URL]
