Hi most parts of the mighty site seem straightforward as access levels can be set with joomla. thus you can separate access of say menu articles modules to users of say site 1 from site 2.

my problem is jomsocial where there seem to be no way to separate groups or hide groups by access levels. which means all the groups in site 1 is also visible in site 2. and like I noticed here users of site1 is also the same list of users in site2 except that they have different access levels.

but going back ... can multi sites hide the jomsocial groups from 1 site to the other?

That's not possible, JomSocial should use access levels for groups itself - only this can help.
