I think you'll get used to #HivePhilly. While different in name, it's the spirit that counts.

Interestingly the Hive account@hivephilly account was registered in c640b5d133a0b868524393c1a2521d1db474ba2c by Hive account@steemmonsters.

Not sure if its a Splinterlands player account or perhaps you or Hive account@yabapmatt registered the name for the meetup?
