currently,there is only an Idea administrator role. However, in organizations where there are multiple business units, this is not sufficient. There needs to be a way to secure ideas to specific uses so that they cannot access other users' ideas. Currently, there is only a filter on the idea list in Version One. Wtih only one role (idea admin) anyone with that role can access and action upon any idea.
This can easily fall in with the idea logged as providing a flexible/more robust/customized security model.
