Invitation only users
Using Jamroom
With restrictions I don't think any spam problems will arise, and if so, it is trivial to solve.
Adding an invitation code field to registration field would be a small task, but does Jamroom support such modifications? Looking at the code I did not find any hooks for observer-concept or anything like that, which would make it possible to make small modifications to exisiting module.
Or is there? I'm very new to Jamroom.
I think further details are more suited to development forum, but maybe an explanation what can and cannot be done would be appropriate here.
