" If you mean "Good time, rollerskaters," (like " that was good time - you're quick! ") then you could say "Vous étiez rapides, patinateurs!" (which literally means "You were fast, rollerskaters! ").
I'm not sure what you want to say with that phrase, it's a little ambiguous, but there's a few options to start you off with. Please comment if neither of those are satisfactory. :).
I am guessing that since you gave the phrase in English you really meant from English to french. Bons patineurs de rouleau de temps.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
