#translatewiki.net the localisation of Toolserver is quite popular; it is not even 24 hours yet and the localisation for several languages is complete. There have been fourteen people active for their language and there are many more languages to choose from when selecting a language on the Toolserver.
When you follow the "MediaWiki CVS" changes, you may have noticed that there has been a steady trickle of improvements to the functionality. Krinkle is doing a great job for us.
The one particularly pleasing thing is the amount of effort that went into the documentation. The intention is to have a quality of such a standard that any Toolserver developer can implement internationalisation for a tool.
Krinkle is quite happy to give a helping hand to the early adopters because that will test the quality of both the software and the documentation. The question is how many tools will be ahead of his "recent Anonymous Activity" tool.
