Continuing the discussion from SoR check in:
Why do players create accounts but not continue to play the round?
One option may be that they just forget.
A simple set of notifications by email (n hours until round starts etc) might help this.
At least this way, if an account is deleted for not logging in, then it’s because we haven’t made an effort to remind them.
Just a thought. Feel free to shout it down as you see fit…!
