michelarielle Hi
By default, the frontpage menu of JomSocial is set to Public, normally, if you don't want a page display in public, you can set the Access Level to Registered Users for that menu item.
Not sure what are Paid members on your site, do you have special user group for these paid members? If yes, you can create a new Access Levels for this user group - same like 'Registered' user group and assign the new access level to the frontpage of JomSocial on your site.
Please note that the frontpage of JomSocial should not be set as default page on your site, you should set another page as default page - which is always set in Public so guests can view your site.
Regards
