I don't think the FA should be tba. Instead, I think it should be tba. tba is much better than tba. All tba is is just the word "tba" repeated 4,500 times. tba, on the other hand, not only does it have "tba" repeated 4,500 times, but it's also got "abt" repeated 4,500 times! Truly something special.
Just sayin'.
