-------------------------
Don't worry, be happy )

• Clearly state what you are trying to do, this means we will have a good background.
• State what exact language and platform you are using (eg. Operating System, Browser, Server Type....)
• Supply ALL error information you possibly can
• Supply all related code, but don't post your whole application.
• Mark where you suspect the problem to be, but include other code that may influence the problem.
• Surround code samples in "<pre> </pre>" tags as this makes it easier to read.
• Don't expect people to do the work for you, we are here to help you figure out solutions, not write them for you
  
• Use a descriptive subject, that way people who specialize in a certain area will read your post faster (eg "PHP socket problem", "IIS error message [404]")
• Finally use the right forum for the question, eg an ASP.net related problem will be answered a lot faster in the ASP.net forum
• And Last, Have fun
