I've heard talk about translation groups, where people team up and translate an article, with reciprocal upvoting and discussion. Do those start organically or is there a spot where people can find others?
If anyone wants to join forces with me, I like to translate articles about science (especially biology) and science fiction. I'm in Tier 2.
I also edit English text for part of my job, so I'm either an asset or an annoyance, as I'm sure my edit history reveals.

I don't know a tremendous amount about these groups (having never participated in one), but from what I've seen, they are generally very inclusive. That thread ought to point you in the right direction, at least.
Edit: That link to the Mar Plateado group was quite old. I replaced it with their most recent thread that I could find, though it seems their activity has fallen off a bit recently.
There's also the Sobremesa Coterie, a kind of spin-off on Mar Plateado. If you're interested in that. Recently we've all been kinda busy, though, so we put it on hiatus for a while. You can still join and translate with some of the members who aren't as busy. (Unfortunately, I'm not one of those, but I can point you to a few.)
Hope that helps. :) Happy translating!
