@Isnigu mentioned on another thread, that in Germany (and a few other countries) use https://www.tabletopturniere.de/de/t3_etr_show.php?gid=143 to track players. Its seems very up to the organizer of a tourney to use the site, but if the community pushed it enough, I feel like we could make this the norm across the board.
It also provides a great way for stores to post tourney's ahead of time so that the players can potentially make travel plans to play across the country/world. I am coming from a United States perspective, but via the link above, it shows the rankings of players across all of Europe (those who use it at least).
It seems to have a couple caveats to it, like tourney's over 18 players require a $40/yr account to post/load results.
I don't see FFG organizing something like this, but if it became widely used, it could be of real benefit. Could possibly make for tourney's to have first round games be based on seeding, which could be fun.

Could it work? Are there other options? I know there is some interest based on several threads around here, but how much?
