I just tried Nabble today for the first time. Pretty good so far. My first time settin up a free forum.
When logged in as admin, I'd like to see an additional option under "options>users>who can view & post". NOt sure what to call this option, but this option would block users from even being able to see that a subform exists unless they are subscribed to it.
For example, my company is tryin to use a forum to allow our clients to view progress of our projects. Instead of our employees constantly emailing, we'd like them to post status messages as forum posts, since this leaves a public and open "paper trail" as to status, dates, etc. Let's say we have ClientA and ClientB, out of 100 clients. When ClientA logs into the top level forum, the only subforum they would see is "ClientA projects". ClientB would only see "ClientB projects". When the admin logs in, they see a whole list of all 100 subforums designated for each client.
As a client, when you first gain authorization into the top level, you would see nothing. Thus, there would be nothing further to click on, get denied, and send an authorization request for. So, instead, the admin would need an "invite" feature to bring in people who can now view that forum.
