User blog comment:Toughpigs/WikiStickies - new feature launching on My Home/@comment-1066636-20091215130110

There's a small bug with the stickies: Long titles with multiple spaces have one of their spaces stripped for the displayed text (the link itself is fine). If you browse through the stickies at Fallout Wiki's MyHome you'll come across multiple instances of this bug. See File:Bug - WikiStickies.jpg for an example; there should be a space between "City" and "Downtown".

Regarding turning the feature off, all that's required to do that are two additional lines in your wiki's MediaWiki:Common.css, adding a setting for it is not really necessary.
