Leveling up
 

Hey guys, I am nearly to level 7 in every weapon...is there a way to level up after your level 7 in cannon, sailing, voodoo, etc?

Sounds like you have basic access to PotCO. For basic users (who've never had unlimited access), I believe the highest level you can have your weapons is 7. You'd have to pay for an unlimited account through Disney in order to advance your character more in the game.
