It's not enough to have options like private, friends, or public in privacy modus. So, public is to much and private or friends is to less. We need an additional level: groups!
If this level will be selected, a second selection needs to be populated: drop down list of all groups, which I'm are member of. And in this, a multiple selection will be perfect. ;-)
Very often, I would like to share Tracks, Routes or activities with particular groups. But not with all group members of all groups at the same time. And not all group mebers are my friends (and vice versa)
Addtional: blogs (travel stories) may also not in every case interest for public. Here it will be also welcome to share them only with groups or friends
Thank you for your suggestion. I will discuss this with our developers, we always try to prioritize certain suggestions on the basis of the number of users that would like to see this feature too. Furthermore, if this is easy to solve we will, of course, implement it right away.
