I found that post, but I find the instructions ambiguous:
How to claim forks
1. Setup a new secure Bitcoin wallet (create backups!), and move all your Bitcoins from your old wallet to your new wallet. To avoid confusion later, label your old wallet (I suggest "compromised for forks") and make sure nobody is going to send any Bitcoin to any of the addresses anymore. Don't delete your old wallet.
2. Wait until your Bitcoins are confirmed on their new addresses.
3. Export the private keys to the addresses that hold Forkcoins.
4. Start with the most valuable fork, and work your way downwards from there. That means Bitcoin Cash comes first, followed by Bitcoin Gold.
5. Install a Forkcoin wallet. Make sure this wallet can't compromise the rest of your system.
6. Import one private key at a time (this reduces the risk if you installed a rogue wallet), and send it to the exchange of your choice.
7. Repeat steps 4-6 for all other forks.
Setup a new secure Bitcoin wallet - but we are dealing with 2 wallets for 2 new coins. I am assuming that if the original wallet was electron cash, it means to set up a new electron cash wallet?
move all your Bitcoins - But since step 2 says to wait until they are confirmed, I am actually
sending bitcoins from the old wallet, which is out of date, to the new wallet and a new address? Because "move" could also indicate to just transfer the private key to the new wallet?
