I'm looking for a solution to critiquing a application that was developed in HTML.

Scenario: End Users look at site and need to make notes about what changes or questions they have.

Similar to using the "note" function in MS Word

If any of you know a way that I can achieve this online then throw me that suggestion, currently the best scenario I can come up with is creating a wiki site to host the notes.

BTW this application will be running on the users machines for the critique, not the web.
