We've been hard at work integrating new discussion forums into the SimTK.org website, and wanted to give you a preview of the new OpenSim discussion forum before it officially launches:  https://simtk.org/forums/opensim

** Please note ** The preview discussion forums are for demonstration purposes only and will not be monitored. All content posted to the preview forums will not be retained after the preview period, nor will content posted to the preview forums appear in the production forums, or vice versa. 

The new forums include threaded discussions, private messaging, improved search, enhanced monitoring/subscription to forums and topics, and more.  We encourage you to test the functionality of the new forums, and would appreciate any feedback.  We hope these new forums will enhance your use and understanding of OpenSim.
