I'm new to MOSS and have been appointed to implement a knowledge base at
work. The knowledge base is basically a couple of hundred question & answers in
a SharePoint wiki, and coworkers will continue to add more question/answers.

We have the wiki in place and the next step we'd like to do is collect some
statistics on what questions people actually use. We'd like to implement a
button like "This info answered my question" that people should click if they
used the info.

I'm looking for tips and pointers how to implement such a button, please.
Perhaps in the future we're looking to do something more like in Microsoft's
knowledge base where the reader can rate the answer and give feedback as well.

Is there functionality in MOSS that let us store statistics from a button click
or what's the approach I should use, please?
