I think we should discourage acronym tags like "tftfv". I assume it means Tales froma Floating Vagabond, but I'm not sure.
We acronymize a lot of other games -- [nwod], [dd], etc. Obviously Tales from the Floating Vagabond is somewhat more obscure but I am not sure where to draw the line. I just created an info page for [tftfv] -- does that ability help resolve your concerns?
