Hello,
I'm trying to make a main website with 4 other sub-sites that are meant to be more or less independant of one another.
The main site is going to have (optionally) a forum, and perhaps a calendar depicting the events on the 4 sub-sites combined in one view.
The only important thing it needs is a nice set of links to the sub-sites (easy enough so far...)
Where it gets tricky:
Each of the 4 sub-sites need a separate group of moderators and administrators
they also need there own forum
their own webform system
their own calendar
and their own file system
with tags relating specifically to the sub-site
And there needs to be an option for a user when they upload a new file to be able to indicate if the file pertains to more then one sub-site. That is to say, if they upload the file on sub-site 'A' they can check a box that says the file is relevant to sub-site 'B' so that the file appears in the file browsers for both sub-sites 'A' and 'B' without showing up in the other sub-sites which were not selected during the file upload.
I have been getting very comfortable with Drupal and I love the functionality. I'm confident that most of the tasks I describe are quite simple and I'm putting together the site now. However, my concerns are in separating the forums, and webforms in the sub-sites while being able to share the files in such a way as mentioned.
