I have barely experience the limitations of words or characters since our locally recognized language is english and in pidgin and from my positing so far I never witnessed that, but from what dunamisx said I think that could also be a better option, after posting a thread you can easily reply as reserved then whenever you complete your translation you can include it there as a continuation to what the previous post is say I think people will better understanding it that way.

Maybe alternatively you can invert them into doc and give it a number to upload them as img by then I believe they could all enter in single page instead of reserving a space.
Do you think about this @op and does it make sense to you as well?
