Leader of Jigglypuff Army
I use only one other Pokémon regularly and it is virtually dead over there. When I mean dead I mean the main page calls ORAS “the latest games” to be announced.
If I have to guess, most people would nowadays chat on online services such as Discord. With these forums being a relic of an era where those things didn't exist yet. That said, it's kinda sad to see places like this neglected like that.
