So, again 
- We did not remove the possibility to play without time limit, we just made it non-competitive (= no elo).
- Please use "Training mode" (infinite sign on the new lobby) if you want to play with no time limit
- For those who want to still get/lose ELO points, you cannot do it without time limit BUT a very good alternative is to play with the slowest speed (1 move every 2 days), and even with that, if some player is over allotted time, you can ignore this and do not expel him/her.
