Extension talk:Translate/Mass migration tools

Feedback
Ok, this looks good enough a draft to seek more comments, especially as you need to write the "use cases" section and that can only be done by hearing from users: so far you only had the point of view of one translation admin, me; I can "represent" most of the concerns from MediaWiki.org, Meta-Wiki and Commons translation admins but not everything. Stakeholders/venues to contact, where you can post an invite to come check your proposal, comment it and watchlist it: --Nemo 12:45, 2 March 2014 (UTC)
