Questions: 2v2 arranged vs random, replays

[CombatEX]

I'm enjoying outwitters a lot so far but I have a few questions.

In 2v2 ladder do you have a separate rank for each arranged team and a separate rank for randoms like in Starcraft or do you just have one 2v2 rank that covers all team setups?

Where can you find other players' replays?

Alex suggested I watch someone's replays, I assume that means I can save them, but how?

Thanks in advance!
