Can you have unregistered trademarks? I know you get copyright
automatically whether you register it or not, but I thought you had to
register trademarks. When there was discussion about changing the logo
(some of the symbols are apparently wrong) someone from the foundation
said that they weren't registered trademarks yet, so we could change
them without worrying about losing the trademark. As far as I know,
they haven't been registered since then.
