Thread:Project:Forum/CategoryTree - information

The "System Messages" / categorytree-member-num part in the CategoryTree page doesn't explain it's usage very well I think. It shows you have 5 parameter options, but not where you should set this or how you can add these settings to your CategorySetup. Also the link MediaWiki:categorytree-member-num is quite empty.

Would it be possible to expand these pages? Or do you think there is no need for it?
