Hi!
Introduce countdown timers for offers at games section which shows how much time we have to complete the tasks before the game(s) disappear.
All offer providers must be made to provide the availability time.
You can allow it to remain unspecified but make sure they have to indicate ~5 days before they remove their offers.
This shameful behavior to put up an offer then remove it after a few hours/days without warning should be stopped!
________
Also indication that we managed to sing up properly should be shown to us always! Too many "looks like you haven't sign up a new account" are happening!
Make all offer provider at games section use these two features!
