I wanted to create a new Game Courier preset to play this Maasai Chess. Then, I follow the link to create a new GC preset. But at the end, the process gives a similar template than for a normal page entry. This is confusing.
I expect you followed the link to create a link page to a Game Courier preset. This is what you should do after you have already created your preset.
So, I started from an existing GC preset of my own, I modified it, I renamed it "Maasai Chess", I saved it and I spent my evening working on it. This morning, I wanted to come back on it and continue ... but I can't find it. Where is it?
What you created is a Game Courier settings file. A settings file may be used as the basis for multiple presets with different appearances, or it may be used as a single preset without modification. After you have made your presets, the next step would be to create an indexed link page to them. To find your settings file, look in the menu under your name for "Your Game Courier Settings Files".
