If you have any trouble, feel free to swing by #supybot and #limnoria on irc.freenode.net or #supybot at irc.oftc.net (we have a Limnoria there relaying, so either network works) and ask questions. We'll be happy to help wherever we can. And by all means, if you find anything hard to understand or think you know of a better way to do something, please post it on issue tracker so we can improve the bot!

We likewise have tons of developer documentation at supybot.fr.cr for your learning adventures. Have fun :)
