Keep your critique respectful.
The title of this thread speaks for itself. When reviewing a Web Site, please employ some common decency by showing appropriate respect to its creator. This forum is not for belittling others regardless of how your perceive their creation.
If you feel something has been implemented incorrectly, explain how it can be fixed rather than simply telling the designer that he or she is an idiot. If you only have bad things to say; don't post at all.
As stated in the Acceptable Use Policy, which you agreed to, disrespectful posting will not be tolerated. I think we can all learn a thing or two from some of the incidences in this forum.
