Board Game Arena

Thank you for the comments.
All my question has resolved.

I had an invitation so I offered a game by selecting "Friends" for the first time.
But I do not understand what is going on now because the massage like
"It's your turn." appears every time I play.
Did I do something wrong ?

I am wondering why Season ends after a few months and all players rank reset.
Strong players have to repeat dull games and average plays may not reach Elite league.
I think that active players would like the termless league of standard ELO rank.

I am a new player of BGA.
In the last game my opponent did nothing and time was out.
Then my move was skipped and I got penalty.
Why did this damn thing happen and what should I have done ?
