Translation in progress... Hi team! I'm happy to translate Dshop in Romanian as I'm going to be launching an NFT agency for Romania very soon. Please let me know what's the verification process of my translation and if there's one. In the past I've collaborated with Wordpress for plugin translation in Romanian and my translations seemed reasonable to them, so I've experience in the field.
