Quick question about the forum

Is there a way to see the full leaderboards ? We can see the top 100 in every category but I was wondering if I could find out about the others players.

This does not concern the Forum, but the Rankings.
Rankings are made with a limit of 100 members, and you can't see the full leaderboards.
If you want to compare yourself with another member, you can check his/her Profile stats.
So you need to check in your profile stats the gap between you and the member in position 100, and make it as an objective, if you wish to be in.

For the moment you only played 1 game, so if you intend to progress in the rankings, basically you need to play more games and send more scores (and proofs) on VGR, and every stats category will be upgraded.
 

That being said, if you're not ranked in first 100 players, we still show your position on the last line of the ranking so you're able to know where you are in the global ranking in any case :-)
