we organized many trips, and now, we are planning to use sugarcrm to implement these needs,
[url removed, login to view] travelers.(it should be a module)
[url removed, login to view] trips.(it should be a module)
travelers can login sugarcrm (not use user account),
and if a trip is open and public,travelers can apply to join in.
and then the trip coordinater (sugarcrm user) can approve/reject this application.
please tell me your similar project experience.
