Wikimedia Bugzilla is closed!

On the English Wiktionary we are currently trying to 
implement via Templates, CSS, JavaScript, and toolserver, 
various improvements needed by a dictionary above what is 
provided by MediaWiki. We currently have nobody capable of 
creating MediaWiki extensions so this is our only avenue.

There are many occasions where we can think of a solution 
but can't implement it because we can't retain information 
between page views. If there was a way for custom 
JavaScript scripts to read and write new cookies not in 
general use on other MediaWiki sites, we could make many 
improvements.
