that message really needs to be fixed. so basically it says ur account needs to be open for some time but it also means u need to play a certain amount of games in order for u to be able to chat.
This site has a problem of people constantly making new accounts so that precautions there to prevent abuse. just play a couple dozen games u'll see ur access to chats opened. I checked ur account and u dont have many games played.
"As a new Chess.com member you are not yet able to chat in this room (to prevent abuse)."
I've had this account for quite a while, and whenever I try to chat, that message shows up. I can't send any messages in any game, even when others can. Can someone help me, please? Thanks!
