I signed up for a free 21-Day Coding Challenge yesterday.
If you're a Canadian citizen, you can win prizes, but that's not my motivation. I want to improve my coding skills.
I learned about the contest from the Women in Web Dev group. They form a team for the 21 days and have some information about the challenge on their site.
But you can also join solo, form a new team, or join a public team.
The project begins on May 1.
