I'm seeing a lot of activity in the issue tracker and elsewhere around MusicBrainz.
Being not too familiar with the project and recent development I might have missed
anything going in that direction, so I'm here proposing to implement translation
tools such as GNU gettext for the superb docs and website of MusicBrainz to
contribute translations online and and proof-read them.
What this could bring is further interest in this excellent project. I'd like to take
this opportunity to thanking you, as well. A fleeting thought.. have you
considered working with the DBpedia project? (I guess licensing in regard to
databases would be the #1 conflict)
I apologise and thank you if there already is an on-going effort.
