Couple of basic / quick things...
1)
Currently all race results get stored on LFWS anyway, but usually they don't tell the actual race result either due to timeouts (endurance racing) or penalties applied after the race (for causing a collision etc.).
So if we were able to edit those LFSW results (adding / removing laps, penalties) those could be used in a common league database to track
a) individual players over multiple leagues (connection to stats: participation in leagues, wins, podiums etc)
b) simplyfy administration for small leagues without own website so they could generate points from those results (also possible connection to news.lfs as those results could be used there too).
This would increase the value of race histories and spare us to reupload race mprs (I'm thinking of huge ass endurance replays here)...
2)
If a league / server is using the remote a simple link on the league page to it, with a timer to the next event (Most leagues have fixed race dates so those could be entered). This could also give the option to alert / remind all entered drivers via a lfs website for an upcomming event.
3)
Similiar to 2. I tend to forget when a league starts (or forget to check their site / forum section regulary), so an reminder to leagues that I'm interested in would be nice (I know this is not directly related to leagues.lfs.net, but I guess there are plenty of crossovers between sites anyway, see 1).
