There is so much more, it seems to me, that just translating word for word, following dictionary definitions. The result has to make sense! Too often the sentences I'm asked to rate are literally correct but are actually nonsense in English.

Both are good ideas, and ones we have thought a bit about before.

A ranking of how good of a translator someone is would help us decide how much to trust their future translations and ratings of others. And of course, a good ranking would give them some bragging rights :).

And while we do currently try to suggest documents in skills that match your abilities, I think people would appreciate it if we could find them documents that better match their interests.
