Soooo I upvoted your previous post, the english version, posted a set of real questions, but never got an answer :( maybe now?

Since HF18 we have to 'redeem' our rewards.

Sometimes I get some cryptic messages in my wallet; What do they mean?

{ "type": "comment_benefactor_reward", "benefactor": "edje", "author": "raymonjohnstone", "permlink": "testing-chainbbs-now-exposed-reward-split", "reward": "542.217451 VESTS" }
Estimated Account Value seems to be not inline with the current price of Steem:

How is the value calculated? Is this a average over x days? Does it include SP, or also the balances in liquid Steem and SBD?
SBD peg to US$

The peg does not seem to be 100%; Lately it is all over the place, jumping from 1.5$ to more than 2$. Any idea what the idea if the idea is to get SBD back to the peg that was initially wanted, ie 1 SBD = 1 US$?
