Terms I don't understand

Hi all,
As a foreigner who only comes here to tour sometimes, there are some acronyms I don't see elsewhere so I don't know what they mean.
What is a spinner for example?
And what does ATF mean - I see that all the time. There are others but I can't think of them now

TER has a "Self Help Center" with lots of info.  

ATF to me is your main Provider you see on a regular basis.  She does pretty much what you want.

I'm not too sure of "She does what you want". You might get the better end of the deal when it comes to YMMV. But that's about it.

ATF = All Time Favorite
Spinner = short thin and petite, as though she could spin around in CG (cowgirl). Kind of an image I like. But then I'm a dirty old man
