Creating New extra roles

Hello, I am in need to create extra roles in my Joomla website. I have already created a 4 different new roles with JomSocial, but they do not show up in the main user roles. I would love to have that done. Or, as I create a new role "teacher" (perhaps with JomSocial), then that role will have pages made available for them (I created them for teacher for example). If they are not within that role, they won't have access to those pages assigned to them; may be a page for teachers, but students are not allowed to see those pages.

Please let me know,

Thanks,

hello the role with joomla social isn't work with flexicontent ....
maybe you can link the same role with flexiaccess ...
(do it for twice)
