Slitherine

After I download and unzip the user made scenarios where do I install them to play on :

1. an iMac
2. A PC
3. Steam

On the PC and Steam it is:
My Games\Order of Battle - Pacific\Scenarios

followed the instructions but the scenarios did not show up when I opened the game and went to scenarios. Attached is a pic of the location where I unzipped them. Did I do something wrong?

Thanks

The three on the top are mine, this are multiplayer scenarios.
You need to select multiplayer from the main menu, logon to the server (use your Slitherine login) and accept a challenge or create one yourselves.
Any entrances in red means you do not have the scenario or the correct version in your scenario folder.
Blue is an available challenge, some of them are password protected (if you want to play a friend and not make the challenge available to everybody).
Brown is your opponents turn in an on-going game.
Green is your turn.
