the Geonet just told the location of people you battled and traded with, id assume that would be easy to implement.
also, im still new to Pokemmo, but is there a GTS? i found the Global Trade Link, but thats not trading, and i need 6 badges to use it. (another suggestion is to lower it down to 4, so that its more accessible to newcomers) but i think adding just standard GTS would be cool, but since im new idk if it is in the game, i could just be not seeing it, and it could be somewhere.
