I used to translate on GIYL for the Esperanto version. This disappeared at some point, and e.g. my work on Gmail in Esperanto has finally never been used. I would love to pick this up again and have Esperanto translations of everything be available. Google products are in use at organizations that use Esperanto as their working language, and not having an Esperanto interface actively hinders work.
