Hi jti899 and welcome to the forum.
There was no fork, if you talk about a blockchain fork.
What happened is, that feathercoin changed it’s hashing algorithm from scrypt to neoscrypt in order to remain ASIC resistant and allow people to mine Feathercoins with ‘standard’ hardware like GPU and CPU without spending a lot of money to buy ASICs.
There has been a group of people who didn’t like that move to Neoscrypt and they created a new coin called ‘Feathercoin classic’ which remained on the Scrypt algorithm.
If you already use the 0.9.6.1 client, you are on the latest production version of the client and all should be fine for you.
If you want to mine again, you may need to update your mining software to allow Neoscrypt for mining.
There are some posts in the mining section which software can be used and how to configure it.
