Thanks for the detailed reply!
By the way, does anyone object to updating the points system in the middle of a season? How about going back and updating the points scores from season 2 tournament 1?
To respond to Stephan's points:
1) I agree, and I also find it frustrating to move up the table and still have the same points. But on the plus side, it does stop the scores for top players from getting too high.
2) and 3) would both work well, I think. The score totals would get pretty big but I guess that's not a major problem.
4) I think it may be only me that likes this sort of system (I love league tables and suchlike for some reason!), but I'll explain in a bit more detail anyway:
Starting configuration would be decided by me probably based on rankings. Two promotions/relegations each season so the best of division 2 should be able to go up quickly anyway - seasons could be shorter too. But perhaps 10 players per division is too few. Maybe 12 or 15.
New players would start at the bottom. Again, I really like the idea of having to work up from the bottom, but I think the frustration at having to start low would be countered by the fact that the player can lead and win the competition in their own division!
I would rather win division 2 than come 8th in division 1..

5) is a separate thing, I think, not related to the above, but I could either do that or perhaps upload more accurate times for the tournaments. Which do you prefer?
Accurate times will be fairer, but will they be more fun/competitive?
I don't really subscribe to the idea of a fixed "invisible" limit for a board unless it can be done in about 3 seconds or less... but your point about tied scores is valid. Obviously anyone can play as early as they like, but being in different time zones makes it a bit unfair.

Anyway, for the points system, please cast your votes:
A) One league - 20, 19, 18, ... 3, 2, 1, 0, 0, 0, ...
B) One league - points for all, one point per place
C) Various divisions, promotion & relegation
