Added

I understood that programming manpower is the main issue for the devs. The advantage of a command is that there has to be some kind of command anyway receiving and executing gui-based configuration options. The latter would mean an additional step modifying and testing the configuration gui, in addition. A commandline command has a tested and working interface requiring no modification exept recognizing the result of parsing as valid (today, it already works reacting with "unknown command" when I enter "/hide guild" or similar.

Anybody interested in more privacy may ask for and will receive answers and directions once the new command will be implemented. If somebody could enter a complete command list into ryzom wiki that would be a good idea, anyway. And it would be nice to have a "/help commands" feature simply listing all valid / commands and a "/usage <command>" giving a short usage overview. Yet I fear that would be a lot of work.
