don't forget @blocktrades - and if you look in your steemit.com wallet, now you can find links at the bottom of the menu on the balances that open up blocktrades with the right pairs set up (btc->steem steem->btc and same for sbd)
In my experience, blocktrades has been the most helpful when things went wrong, I was never in the lurch for more than two days, and sometimes, they were even MY mistakes!
