Hey there :)
I wanted to ask a question...
Let's say there are 2 people: Peter and Paul.
1) Peter goes to my app and authorizes it (stream_publish, offline_access and everything else what's necesary).
2) He is now in the app and let's say there is an option like this: Send gift to your friend Paul.
3) Can we post now on the wall of Paul, even he didn't authorized the app?
Thanks for all your answers, Really apprciated :)
