If you had bitcoin before the fork, you'd have some of the fork, right? How do you access something like that?

If you hold the the private key of the coin, simply download the forked coin client and sync with the old key. The money should automatically appeared.

The story is more out of control if you hold the money in the trader. Since you had to rely on the trader to enable support for that new coin, which may happen later or not happen at all.
