About the only topic that is really taboo (but of course still happens) is being a jerk, or treating people unkindly (there's other things as well, but I would greatly hope that you'd be smart enough to know that such topics are not welcome almost anywhere...). In other words, you're welcome to talk about just about anything. Of course, the best way to find out is to read previous threads and such. Mouser X over and out.
