Hallo Joseph,
Well, personnaly I think that adding an entry is still different (it's another botton, too). They always CAN undo what they have done by EDITING it (even if the three things were seperated).
In my case, for exemple, they have to do collaborative work:
I create some entries first (so they will understand what it is about with concrete examples); after, they edit these to add their "definitions" (which are linguistical contexts, in my case) and add other entries, then others will complete these, and so on.
But they could click on the wrong button (that's human) and delete all their work on that entry...
I hope you understand...
