establishing roles after importing from phpbb
I apologise in advance if this post is hard to understand, I have pretty rudimentary computer skills, but I do own an online community that recently imported a forum from Phpbb into Vanilla because I found the former too complicated. I managed the export with help, but then found that instead of getting the list of default roles that is shown in the Vanilla documentation, I got only some (most significantly, Applicant was missing), as well as some imported from Phpbb that I didn't want (like bots, for example). The problem is, this community is private, and no matter what I do I can't seem to set up the roles so that only registered users can see content. I want a category where applicants are just that, people waiting for approval to use the forum.
I know you can add roles, so I've done that, but I'd like someone to tell me exactly how to configure it so that no-one except registered users can see the forum's content, and applicants cannot -- I've had a couple of more computer-savvy people than me try, but so far it's not working and we don't know why.
