What version of WordPress are you using?
Do you have any plugins that modify user roles or permissions in WordPress?
I don’t have the roles when adding a user form within the wordpress admin (I need this)
But I do have the roles at the very bottom of the page when editing a user.
No plugins that modify user roles or permissions, Version 3.5.1
bbpress roles are automatically assigned to new users as set in bbpress settings, after a new user has been added you can then change that users role via dropdown menu near the bottom of either the wordpress profile or bbpress profile page
Sorry, all is OK now. I overlooked them because of 2 reasons – they are at the bottom of the page and they appears only in the user edit page.
