Participating in the OpenSim Community

OpenSim is an open source project. This means that it is developed by anyone who wants to participate. This could be you! We welcome testers and developers alike. Please see the Contributions Policy for more details.

If you need help or want to help the best way to get in touch is via the IRC channels.

Getting online

There are several public grids and several standalone arrays running 24/7. For the casual user as well as those who want to run their own public regions, there is a list of available sims at OpenSim: Grids. Most of these grids have representation on the #opensim chat channel for asking and answering questions.

While OpenSim is not affiliated with any one grid there are many prominent Grids.

Mailing lists

Various mailing lists are available for communication between users and developers. A list is available to subscribe to email SVN commit notifications.

• opensim-users - a user support forum for OpenSim
• opensim-dev - development discussion of OpenSim
• opensim-commits - an email list for svn commits

Bugs

Please use the SecondLife official 1.18.5.3 client on Linux, Mac OS X, and Windows- third party viewers and modified viewers add more variables to a bug, making it harder to track down. The bug may not even be an OpenSim one! Make sure you use only the official client. See notes on configuring your client over at the |client setup page.

You can report bugs at the Mantis bugtracker.

Note: Some email providers are tagging Mantis emails as spam. If you sign up for a Mantis Account and don't get a confirmation email:

• Check your spam folder, see if it is there. GMail is consistently tagging these as spam.
• If you are using Yahoo, you'll need to wait ~ 8 hrs to receive any email from opensimulator.org.
