CiviCRM Community Forums (archive)

I think you will need to do some custom code. One potential project which might meet some of your needs is merci:

There is pretty decent civicrm integration with merci (thanx to krenyen @ merci and oliver g @ gmvco), so i would definitely check that and potentially chat with krenyen

This is something we would like as well. Our needs seem to fall between those proposed in the CiviVolunteer module and those needed by Chiebert. I would be happy to contribute to a Make it Happen for this.

One thing to consider is how events are structured. For example consider a soccer tournament:

There are games that need fields and referees and line judges.

There is also the overall event which needs:
    Setup
          line the fields (put down the lime used to mark the field boundaries - for those who have never had to deal with this :-) ).
          install the nets (goals are usually there, but nets are removed and reinstalled for matches).
          deploy trash cans
    Checkin for players/teams
    Ticket sales
    Security/Ushers
    Concessions

This is the same for a convention or a conference. Some of these might have a single event (from a CiviEvent stand point) where guests register for Foo Policy Conference and can attend any session over the 3 days, and some might be multiple events - each session is a separate CiviEvent.

A scheduling system that allowed the creation of templates made up of templates or one time tasks would be great. That would mean that one could create a soccer game as a template, and create a tournament as some one time tasks and 3 "game templates" that could be saved as a single master template. This would be really useful for organizations that host similar events often.
