Once you have the token you need to enable staking (there's a diamond icon in the wallet if you're the issuing account). You'll have to set the unstaking period. This too can't be changed. Make sure you set the unstaking longer than the time to recover your VP. So, if it takes 5 days to recover your VP after voting down to 0% make sure that unstaking is slightly longer than that. You have to burn 1000 ENG to make a token be allowed to power up.

Was it always 1000ENg to enable staking? or is enabling staking free, just 1000ENg to allow power ups? so is that 1000ENg the total price? If i for example have my SAND token i already paid for, its running as a simple token on steem engine, i never enabled staking, is that feature now going to cost me to enable staking? or just to enable staking + Power ups?
