Jeff has the right idea based on
Even You Can Do It. Take some code and do something with it. He mentions that OpenACS needs work. Sure it does. All software needs work, but you never know just what it needs until someone actually uses it. That is why I released this web site way back last year on a pre-beta copy of OpenACS 4.5. It mostly works, and I sure learned about the toolkit. One thing I need to do is migrate this all over to 4.6 and keep better track of the code base.
