How to manage the validation of Group/Blog article/Event publication?

Hello

1. is it possible to remove any 'validation step' to publish Blog article or Group or Event for ALL users ?
- using a setting in the back-end I suppose?

2. is it possible to remove any 'validation step' to publish Blog article or Group or Event for SPECIFICS users ?
- I think we can do that from the front-end since the last version of Easy Social ...

Thanks
Henri
