I have this dibsed ;)
We should have a day when we organise the Dojo Master from last year to come in and sign autographs and stuff. Or, let him help with the Dojo League.
In all seriousness, I'm excited for the expansion and think only good will come of it for both them and us. Hopefully, someone will do a large Forum FFA, without any special rules, to welcome them. When I first joined, I came joint last with a Cleffa, but it was still really interesting and fun to observe.
