One of my friends runs Botwiki.org and hosts a Monthly Bot Challenge. I figure some of you here may be interested.
The theme of the challenge changes every month (last month’s theme was “Spaaaace!” and this one’s theme is Emoji).
You don’t need to be an experienced programmer to join our challenge; actually, making bots is a great way to learn how to program! People voting won’t see your code, rather they will judge your work based on your creativity and overall execution of your idea.
