First: I just joined and I absolutely LOVE this website!
After looking through the requests, I have to say that I came across some old requests (a few months old) that would be really, really easy to translate (things like "I love you." ) , but nobody has translated them yet, just because they are set to "high quality needed".
So instead of getting a high quality translation, they got no translation at all!
Wouldn't it be an idea for members to be able to offer a "non-expert translation" as an interim? - But the request stays online until an expert does the final "high quality translation"?
But this is just an idea. Sorry if it's not a good one.
