The project page at our.umbraco.org is rapidly being filled with some excellent packages (even looks like we'll need to split them in categories, since the projects list is getting crowded).
Since we now have a clear overview of the projects and their value for the community (don't forget to hit the 'thumbs up' if you like a project) we'll be updating the package repository more often.
For our first update we've added 5 of the best rated (and stable) projects.
You can now download and install these directly from the integrated package repository.
