How to get a translator tag?

Apologies if this is mentioned somewhere.  How does someone get the " Translator " tag on roll20?  I've assisted some volunteers from the community in implementing a handful of translations on various sheet's and I would expect they would get some recognition for their efforts.  I thought that the sheet.json might include a "translators" key but after comparing various sheet.json files, that doesn't appear to be the case.  How can we help these translators get some love? Thanks

From what I can gather (from Felipe, who helped translate the Savage Worlds Tabbed sheet to Italian), they'll need to contact the Roll20 team via e-mail. There's a test of some sort and once that's all taken care of, they'll get access to Crowdin (or something like that). 

I wonder if this can be done after the fact...?  Thanks for the info Finderski.

I think the translator tag is for those who help translate the website, not the character sheets.
