I am looking for bulletin software preferably that I don't have to modify much to fit my needs. I just taught a robot camp for kids and would like to have a forum/bulletin for the kids to post on.
I would like this bulletin software that can be easily customizable for a private list of members. Members should join by invitation only. I'd prefer for an open sourced solution in PHP.
I have phpbb2, and it seems I'll need to add a mod to get it working as I'd want.
