Redmine

This would break the clear permissions given to a user with a certain role in a give project, and would break the ability of users with the permission to manage users to have a complete control over members of the project. I suggest making groups with the users you want to add with a certain role in projects and do it with groups.

Hi Felix,I've got a problem somewhat like Bruno.In my company situation,a project may have 40-50 subprojects,but the members all act on the same roles,If I want to put these guys with the roles in all the subprojects,that was really a huge work.So I wonder if there was a function that one project's Members and its Roles can be selected to apply in other projects,that would save a lot of time
So,is there a way to work this out?Any suggestions would be appreciate!

Same answer as above. If you have such a degree/need of customization/behavior change, you'll probably be better of developing a plugin for that functionality.

Also, please don't assign issues to people on redmine.org, it's rather the people who take care of doing something who set it to themselves than the other way round, thank you.
