I read this:
https://github.com/SimpleMachines/SMF2.1/issues/2641
It looks like https://translatewiki.net/ may be an interesting way to get new translations (and advertise a bit the project as well :P).
What do you think?
I have no objection so long it is user friendly. I hope it is equivalent with the one we used right now.
Honestly I have not investigated much (I just registered, it makes you translate 20 strings, probably from random projects to... dunno, likely verify your skills and contribute something).
What I was thinking while posting was to make it act more as a "support", so have transifex as reference and this as help, especially for languages not very wide-spread that could get some more love from a wider audience of translators (the project is used to translate WikiMedia, so it has an established community of translators).
I'll try in the next few days to contact them on IRC and see what are the terms.
