Here i actually got a push notification, but there is no actual notification in my records. I don't remember if last time it happened it was a push or normal notification.

EDIT: clicking on `referrals` in my profile does not show any new referral for today. Maybe a bug?

Your profile or any item of yours is an implicit referral link so yes.

However, I noticed that I sometimes get a push but no normal notification. Do you mean push or normal notification?

So far not sure how this could happen but will look more into this.

I sometimes get messages that someone joined SN because of one of my referral links. Even when I have not been posting any such link for a while. Would a possible explanation be that people would have joined SN by clicking on one of my SN posts that shows up when doing a Google search?
