Thank you for the post, I'm not clear about SBD, how can I make conversion request ?

from your post
When a user requests a conversion from SBD to STEEM their request is delayed for 1 week and then executed at the future
moving median exchange rate. This process ensures that no one can use the feed delay against the network.
Conversion requests will primarily be used by speculators looking to buy large quantities of STEEM without moving the market.
