This is the entire project: The component (com_opensim) including the current modules (mod_opensim_events, mod_opensim_friends, mod_opensim_regions and mod_opensim_gridstatus and mod_opensim_admin) and the plugins (plg_jopensimregister and plg_jopensim_quickicon). There is no need to unzip the file first. This zip will install it all in one go!
