Try not to spam the main channels; your bot can sit in them, but please keep as much bot chatter to #bots as possible.
Test your bot; either make your own channel, or use #bot_test, to make sure your bot is behaving well before inflicting it onto your fellow tilders.
Your bot should respond to !rollcall with a report of what it does.
Your bot should never respond to !rollcall with !rollcall.
More here later.
But basically just snoop other people’s bot scripts and ask questions in IRC.
