I am currently the coordinator for Estonian translations on Transifex for Django itself:
I would also like to help translate DjangoBB to Estonian. A week ago, me and my friend (pajusmar - also in Django Estonian team) made requests to create the Estonian language on Transifex. The “Estonian (Estonia)” translation has since been created, but I am not a member. I think that should be changed to simply state “Estonian”, without the country specifier. I originally submitted a request for the wrong thing, sorry.
And can you add us to the Estonian team on Transifex?
