Facebook users know they can get poked by a friend, but how about getting a nudge from your friendly neighborhood process server?
This is happening right now in Australia.
I find it hard to believe this can be legally binding; after all, how does the server know the intended party will see the notice? In my case my wife can access my Facebook page. For all I know process servers are lining up on my wall, but to keep me from getting upset my wife is somehow getting rid of those entries. She is wonderful that way.
