This is the only forum that comes to mind sadly. I've seen a few other forums, but the people there are overcompetitive and unfriendly.
This forum's great of course but I want to also join a full Pokemon centered.. I know how it is though, a few I've joined before didn't have a good vibe to them.
I understand what you mean. Perhaps you can try a general google search for pokemon forums and you might find a good one that way.
pokecommunity is a good Pokemon forum. People there are friendly
