Captain:
Will be releasing Atlantis testnet in less than 48 hrs. We plan to use snapshot of existing mainnet chain for tests, confirmations and verifications.
Tests would be running for week and users can evaluate everything before moving to mainnet. Users can create wallets from existing seeds or create new wallets and test everything their own.
Pls report any bugs/crashes/etc. during the tests.  More details will follow before 48 hrs.
