In terms of the DNN forums there are a number of moderators (such as myself), who tend to be well regarded community members, DNN MVP's or DNN Corp employees.

In terms of projects, you can always look at the relevant team page e.g. https://dnndocuments.codeplex.com/tea... . Whilst this doesn't identify Mitch as the sole project lead, the other's in the coordinator role are there primarily as legacy members, or from the days when the documents module used to be shipped with DNN itself.

For projects that used to be a part of DNN, we do try to follow them and if they are stagnating request the project owner find a new project owner, but as they're independent we have no control over that. That said documents had a release only a few months ago so it's in reasonable shape IMHO.
