Major Description
I would like to see the ReferringUndefinedPagesPlugin as one of the core plugins.
See http://www.ecyrd.com/JSPWiki/wiki/ReferringUndefinedPagesPlugin for more info.
The code is just a few lines: http://www.ecyrd.com/JSPWiki/attach/ReferringUndefinedPagesPlugin/ReferringUndefinedPagesPlugin.java .
The original (non-core) plugin was an idea by Gregor Hagedorn.
Juan Pablo has already tried contacting Gregor if he allows us.
If not, we will write it from scratch.....already done with some enhancements and unit tests, see attached patch.
