Google is running their Summer of Code (http://www.google-melange.com/gsoc/homepage/google/gsoc2012) program again this year, and Horde will apply to be a mentoring organization. This page is a guide to participating with Horde, and the place to collect ideas for projects. It is mainly for those with project ideas and those interested in participating as a student. If you'd like to help out by mentoring, send a note to Horde's mentor coordinator, Gunnar Wrobel (wrobel at horde dot org).
If you are interested in participating as a student, please join our development mailing list (http://lists.horde.org/mailman/listinfo/dev) and say hello!
