I have mentioned this too, long time ago. It's essentially, to get this feature if you will have Events. Subsequently, ther is a naturally need to share common experience with all event members. But seriosly, in most cases only with team- or event members!
Not only German Law about data protection, does not allow to share private information or fotos from people without their consent form. In other words: as organizer of an event, you will not be able to share any information of the event, as long as simply one member has not giving his formal agreement. But many people are willing to share it with team or group - but not all the time with total public!
So please MRA developers, implement for event, blog posts and travel stories sharing options. We need privacy mode options: private, for friends, for Group, for event, public.
