Ruby Rookies are gathering on Thursday evenings during March to learn to code Ruby using Project Euler (http://projecteuler.net/progress).
This is volunteer sign-up only. The event sign-up is under the Ruby meetup group:
Would be great to have a few mentors (2-3 or more) during any segment of the 2-hour gatherings to serve as resources, in case people get stuck or talk about programming in general.
It would also be a great opportunity to be an ambassador to the community, and practice what you've learned as a student by acting the role of the teacher.
