bbPress.org

I’m running a WP multisite with bbPress installed on the main site. When new users create accounts on the network, they are assigned a role of Participant, both in the network and for the main site. If they chose only to create a user account and not a site, once they have logged out after their first login, they are unable to log into their profile pages. It seems the default user role of Participant is not recognized as having any privileges by the WP software. When I manually change the user’s role to Subscriber, they can then log in to their profile page. Obviously this is not a long-term solution, so is there any way to revert to WP’s native functionality of making new users subscribers by default while having bbPress installed?
