I'm very excited to publish Societo, a open source social site platform, is based on Symfony2 standard edition.
Unfortunately, current Societo may be too buggy and there are some missing features (e.g. implementation of ACL is not completed, so it doesn't support to delete posts yet). Please wait for using Societo in your production server. I want to implement some missing features by first development release (I think it will be released in Oct.).
Societo is developed by myself so far. Of course, as you can imagine, it will be very hard work. I need many helps from open source community to raise Societo.
Societo is hosted in GitHub. Please fork it and give me much pull request. And also I want to manage issues in GitHub. If you find bug of Societo, please report it using GitHub issue tracker.
While your playing with Societo, I will work hard to construct development rules and to write documents for our contribution. I will share my idea with you in the development mailing list (I'll create it soon). Please subscribe it and give your idea.
