As has been explained in several other such threads in the last year: localizations of the game are not ‘one and done’ efforts. CCP has to have a dedicated bilingual support staff for each localization, including ISD members for language-specific forum sections, GMs for Rookie/Help Chat and New Player Experience support, and translators for new in-game content (from UI elements like settings menus to mission agent scripts, NPC call-outs in local, the Agency interface, all the various windows, and so on).
Direct quote from @ISD_Dorrim_Barstorlode:
It never hurts to apply at https://volunteers.eveonline.com/ if you have language skills. More than one team could use them.
Encourage English/Spanish fluent players to apply to the CCL (community liasons like ISD), STAR (player support like GMs) and LOC (localization effort) programs. The first stepping stone is generally getting a couple ISD members who can moderate a language-specific sub-forum; after that proves out and some GMs are brought on, we might get a language-specific help chat in-game. Only after both of those are sustainable are we likely to see any traction on a full-game localization (due to sheer effort required to create and maintain the localization).
