Aid Development for Peercoin
http://peer4commit.com - A brilliant service bringing developers and people who believe in Peercoin and want to help fund the new development of Peercoin and associated services. If you are a “Owner” of Peercoins that wants to see a rise in the value of PPC then I urge you to donate to projects that you would like to see active development on. If you are a developer there are many projects in many languages, all open source, so you can have a look at the code, github issues etc and make pull requests to the official repos and for each commit you will receive 1% of the total donated.
