Hi there,
first, is that a real username or we already have a bugmenot account for this?
Anyway, i think mai already gave a good introduction to it, i understand what you said and the problems with it (basically, redundant text and unfortunately extra length in filenames), but on the other way TNC is already confuse and complex and adding those alternatives wouldn't help in my opinion, you can read what was discussed some time ago
hereAnyway we're always open to suggestion and want to make things better, there are a few aspects in TNC that still need to be cleared out or fixed, it is far from perfect
As for the filename in question of your example, i don't know much about most of the systems but from what i know most of the times some group cracked it and other trained it for example, since various group names appear in the game it can lead to mistakes thinking that all groups were involved in both crack and training, but it isn't always true
