Here at OSTraining, we're enthusiastic users of ManageWP. We have an in-depth video class on using ManageWP and use the service to maintain our own WordPress sites.
We're delighted to have hosted a webinar with Nemanja Aleksic from ManageWP.
We recorded and edited the webinar, and have published it below.
This video has something for everyone, from ordinary WordPress users to experienced developers. Nemanaja talked about ManageWP tools and also about the challenges of a project that involves overhauling such a popular system. If you're really interested in project management in the open source area, check out UpStream, a WordPress project management plugin.
Currently ManageWP is in the process of launching Orion, a completely redesigned and rebuilt version of their platform.
