When studying a web page, the common problem is that users notice a
mistake, or feel that some vital information is missing, or do not understand some
explanation or wording. The possibly supplied list of frequently asked questions and
answers is often not helpful, and trying to contact the web administration can be quite
frustrating. In this note, we discuss methods that make it easier for users to send and
receive meaningful feedback from a web server when needed. The problem is that the
system has to be easy to use, yet must avoid misuse by a possible attacker and that the
server administration gets valuable feedback, yet is not overwhelmed by the requests.
After studying and experimenting with various techniques, we report on a solution
that allows users to send feedback or ask questions, yet remain anonymous if desired,
and also protects the web server by filtering feedback and questions using language
recognition techniques. We propose and report on an implementation that makes such
feedback mechanisms available to users whenever they feel the need for it.
