And I also got another question : how do GT3 EURO work ? I mean I join it on Watkins Glen, so on the last races, so I can’t be one of the best, but when this « cycle of circuit » will be done, what’s going to happen ? And when will it restart ? And how can I call it ? A championship ? A league ?

The Historic Standings page shows what series there have been in the past. That'll give you idea how things have changed between series, which probably tells what changes to expect next. Alternatively, go to Forum/News and look for threads titled "New Assetto Corsa series starting <date>". Also, from the forum it seems that new series have been published two days before they start, so you'll get your definitive answer soon anyway!
