Wow, wow, wow!
It's a fantastic feeling to ask some question one days amd have the solution in the next - with advice or by a new feature developement!
I have several questions in PM, may be interesting for C2 users:
1. You may a Clay.io login box appears just after your game is loaded. To turn it on/off look at the Clay.io/admin/Yourgame/Settings and check/uncheck "Always show clay.io login box on load when a player isn't logged in".
2) I did a mistake, and recorded about 6000 score submits in several seconds from C2 preview. Now there is a new "Clear Scores" link in the Clay.io/Mygame/Leaderboard screen, so this kind of bug may be solved...:)
austin - I think the data is not removed from the statistic graph's tables.
3) Now this is clear in Clay.io/MyGame/stats that the first stat type "Views" is how many times a game was loaded in a browser. And the "Plays" is how many times a user played a game.
The first one is auto incremented, once your game is loaded (with Clay.io plugin)
And we have an Action for the Plays: "Log Play" in C2 plugin.
4. We now have an Action to get the Leaderboard date in the background, and show it for our gamers in the game's design.
Do not panic, if you can not find Fetch Leaderboard Object action, it will appear if you try to add it in a For Loop! :)
(You will need to download the new Clay.io plugin!)
