I am working on setting up the translation portal. I am making some changes
to the original GlotPress on two fronts (1) make it more effective for end
users in general, allowing more control on database than product offers in
subversion (2) strong integration of Elgg language stuff into the core.
Yes, the idea is that both core and plugins can be managed by a single
installation of the product, so anyone can really just use it for their own
plugins and then whoever would like to translate can do from one
centralised portal for anybody's use.
Will post again when I have it up and running... shouldn't be long ;-)
