Re: New at Aikido
My dojo has a very brief one-page handout explaining the most common points of etiquette as practiced in our dojo - if your dojo has something similar, that's your best reference. If not, you might take a look at some other dojos' etiquette info (you can probably find quite a few on dojo websites, or I'd be happy to share ours if you'd like it). Bear in mind, though, that practices vary from dojo to dojo -- some dojos line up with seniors to the right, others to the left, and that's just one example. Etiquette and culture are definitely a "when in Rome" thing.
