Can I join the VivoSim grid?

Currently the VivoSim grid is just used to host a few regions and does not accept user registrations.  The VivoSim system and website does allow you to link your website account with an avatar from any OpenSim grid, so if you don't have an avatar yet you may find the information in our guide useful, see https://vivosim.net/help/guides/user-guide/detailed-walkthrough
