I have a general comment
firstname.lastname@example.org or the component feedback survey (View->Other Windows) are great places to make suggestions but bad places to ask questions or get technical support. You can also make suggestions by opening a technical support case. Many times those guys know a way to accomplish what you are asking for in another fashion.
Another word about the component feedback survey, it's hard to tell where to leave feedback, but there is a space for comments.
