Yep Santi, using the complement method, by only labeling official names would also work. I am under the impression that it is more common in publications to label unofficial names instead. Well, we do have a different situation here where unofficial names vastly outnumber official names, and hence the "officially named" group would have fewer members.

It may seem weird for readers at first, but after a while they will also get used to the special convention on Nitrome Wiki.
