Access requires permission from Dave

Add contact

Inspired by Jyri Engeström

Should any of the selected types be protected, I will be asked whether I want to request access

If yes, an OAuth request will be sent which Dave will later be able to approve, deny or ignore

...And Dave’s public activities will show up in my activities dashboard

...And if Dave approves my request, his protected activities will show up later

More soon at activitystrea.ms
