You can still look up shedules, results and standings from leagues that are no longer active James.
In your team overview there's the Leagues tab with all the leagues are listed you once were in. Hovering over the links will give you the league number. Once you have that, it's easy. If you go tho the schedule or standings page of your current league and replace the league number in the url, you end up with the one of the league that's no longer active.. :)
In yours I see FIA Formula One World Championship for example that has this link: http://igpmanager.com/play/?url=league-info/3658
The schedule page of the league you're for example in has this link:
http://igpmanager.com/play/?url=league-schedule/3956
Replacing numbers will give this link:
http://igpmanager.com/play/?url=league-schedule/3658 and with that also a possibility to look up your old results of inactive leagues.
And no, all championships should count. Mine is mentioning only 30 though while it should be 38.:)
