I was wondering whether anyone can recommend anything in existance that can do the following:
Blog software/CMS to:
- Manage multiple user groups who each receive private, customised posts (when logged in) - Facility to post specific news to different groups - Groups can be defined in a tag-like system (e.g. post to all "red widget" and "blue widget" members only)
I think you could do something like this with Drupal. I am currently working on multi-site configuration (single-sign on across various sites). I could see you having various "sub-sites" where each group has access to just their sub-site... but all under the same user tables...
