The Bitcoin Private (BTCP) Fork snapshot will happen February 28, 2018. No block released yet but the snapshot will happen on a block during that day. However many BTC and ZCL you have in your wallet at the time of the snapshot, you will receive the same amount of Bitcoin Private (BTCP).
The BTCP team is not allowed to talk about exchange support so an announcement on BTCP exchange support will either come from an exchange or third party.
The ZCL Electrum wallet has been released and can be downloaded at https://github.com/BTCP-community/electrum-zcl/releases/tag/Z!1.0.0
