The block for the fork needs to be announced in advanced.
There are miners on the main chain and this is a community coin.
The main chain is at height 311152 and has been moving all day.
Kindly don't ninja hard fork.
I'm not in control of the code anymore but i passed it on, here's what i was told (I'm just a messenger in this)
"We need people testing that diff adjust fork. We want to fork ASAP tell them they need to give us a fork date, if not we will chose it."
