Skill building group

I'm ambitious yet have a difficult time with self-motivation. To solve this problem, I'd like to form a skill-building group. This way we can come up with tiered projects, starting with simple things and working up to awesome solo projects. Technically this could be done by simply building a list of projects to work on, but I'd like some kind of deadline setup as well, which a group could provide.

If this fits in a different forum better than here, feel free to move it. I wasn't sure where to post it.
