channel naming conventions

Hi, We need to come up with naming conventions for channels to help avoid conflicts. A prefix could be used to distinguish private channels from official channels. We could require all private channels to prefix with "_", as in "_chiara" for the random private channel that distributes packages for the unofficial "chiara" channel located somewhere in Italy. This would avoid any confusion with the "chiara" channel for the unrelated public channel that is (will be) registered at pear.php.net. Alternately, we could recommend that all private channels be named after their server as in "chiara.example.it" and only public servers would be given nicknames that differ from their server. This seems most practical to me. Any brighter ideas? Greg
