Find what, where? There's two types, Ironclad online which is like playing over LAN, seems i have to add players manually and LAN Multiplayer which is what it says. Wish there were something like blizzards bnet. Even Diablo 1 have better multiplayer capabilities and it's 15 years old!!!
Ironclad Online works, but its a bit confusing at first it may look like there is no players there and you need to "add" players.
What this actually means is you have to choose a player name for yourself to use in the games, and type it in the empty player list then click "add player" to add that name as a usable player-name for you.
You can then click "use player" to connect as that player-name, to the chat lobby and/or use the join games
