Theodore, Do you already have a m-to-m between User and Project? Or is assumed that all users have access to all projects?
If all you need to do is decide who gets emails for a given project then a simple m-to-m will do. i.e: User <<--emailRecipients----------projects-->> Project Any user in the project's emailRecipients array will receive emails. If you already have a m-to-m between User and Project, then you will want to add a flag on the join table (isEmailRecipient) and expose that table as an entity. But! You also will have to unflatten the m-to-m relationship and treat it like the individual relationships and entities that is is. EOF will cannot handle a flattened m-to-m relationship if you need access to the join entity. i.e: User <--user--projectDetails->>ProjectUser<<--userDetails---project-->Project How you choose to implement the UI will depend on how you end up modelling this.
