Hi Richard,
Sorry, I don't think there was ever such a list of projects on moodle.com.
Anyway, the best place to "hook up" on these things these days, whether you are a developer looking for paid work, or someone looking to pay a developer, is on the Moodle jobs board.
Also, specific small projects intended for core Moodle should be listed in the Moodle Tracker etc regardless of who is working on it, just so everyone knows what's going on.
More info can be found here: http://docs.moodle.org/en/Development:Overview
