@murilopolese thank you for sharing patchstorage.com. I am one of the members behind this project and it is really nice to see people engaging in it.

Few updates from PatchStorage:
We have just added Explore section to our site. You can easily filter patches based on their category, state or platform.
http://patchstorage.com/explore/
Also from now on you can choose from different project states - work in progress, ready to go and help needed. If you are stuck with your patch, just choose "Help Needed" and you will get support from our community.
