All right. I'll copy & paste Japanese translation from .jp wiki to ..._(ja) page of techbase.
You don't mean that I have to add <translation> tags on ..._(ja) page and/or original English page, right? Let me ask to avoid misunderstanding...
I'm thinking aloud, and it may not work, but I'm suggesting that we put it onto the Japanese pages. It's nonsensical to be there, which should remind me that I have to manually deal with them. If you have any better ideas I don't mind - I just want something to remind me :-) It won't actually cause them to be in the translation system, as someone (usually me) has to mark them ready for translation.
