I (user "samer") have an issue with user "senrof21". If I go to " http://kune.cc/#!senrof21 " it appears the button "Write to your buddy", as if we are friends. However, he doesn't appear in my "buddies" list, nor I appear in his. And when any of us clicks in the button "Write to your buddy", this message appears:
"You do not have rights to perform that action. You cannot write to non buddies"
His "buddy" list is hidden, I don't know if that's related. Maybe more experimentation is needed.
