Proposed projects


A good first point of contact is the OpenSim IRC, on channels #opensim / #opensim-dev / #osgrid / #opensim-scripting. The OpenSim developers hold office hours once a week in-world on Tuesdays at "Wright Plaza" on OSGrid. There is a "Test Hour" on Saturdays, also generally on "Wright Plaza". Both these weekly events are held at 1900UTC in summer time and 2000UTC in winter. Check on the #opensim IRC channel on Freenode just before each of these events if there is any confusion.

There is also a mailman email distribution list available at
