Learn how easy it is to sync an existing GitHub or Google Code repo to a SourceForge project! See Demo
Would be very nice to support opensync so that one could synchronise various devices and even software that has opensync support.
I think sync should be left to modern and standard protocol like CalDAV.
See https://sourceforge.net/p/osmo-pim/feature-requests/121/ for discussion about what protocols should be supported.
Closing this for now.
