I have shut down the one remaining seed node.
What are the 2 things that needs to happen to save this coin ?
I don't know what you mean by 2 things. I alerted Leigh to your post on Twitter but I didn't get a response. His bitcointalk account looks to have been hacked some time ago, but his Twitter looks fine. I won't post it here in case he doesn't want me to.
To get development on Britcoin again, you would probably need to get Will, Leigh, and Darryl to either burn their coins, provably give away their coins, or work on the coin. I would try contacting Will (via Cryptomate?) if you have a plan for development.
Perhaps Vanity Wallets would help with a "Britcoin Classic" if anyone wants to do that. I'll stay out of Britcoin's way from now on.
