I suppose like many others I have a defensive registration at Facebook with just a few posts etc, I haven't done anything since last September 2014.
Wanting to check the new Facebook logo I clicked on my company site and there it wasn't, it had been "closed or removed"!
I logged into my account and sure enough everything was there however it said that it was unpublished so I published it and, hey presto, it returned.
So the question is do I have to log-in every 3/4/5/6 months to keep it active?
