Setting up ProSites, Buddypress, and other pages

Hello
I am confused when it comes to setting up pages for login, logout, account status and other pages for ProSites and Buddypress and other plugins. With the Membership2 plugin, the pages are easy to see in my list of pages. I know to assign those pages to specific areas. I have granted support access and would like help in this area for setting up my site and these pages for ProSites, Buddypress, and other relevant plugins.
Thanks
Andrew
