Any way for contributors to add new sets that haven't been updated on the site?

Have a couple TCG/CCG set requests :)

One Piece: Wings of the Captain OP06

Digimon TCG (the original US version)

Digimon Cards made by Upper Deck

Pokémon TCG other language cards besides English & Japanese (French Base Set + Jungle and a slew of different recent Korean sets)

MLB Showdown 2000-2005 (including additional Trading Deadline and Pennant Run sets) added + move existing sets from the sports side of the site tree to here (or able to include in collection total)

I could go on if the ability was added or the above sets could be added I'd be thankful

So I can use this as inventory management and market, and seamlessly integrate with eBay
