Hi MeridionaleDG...Welcome to GC!
There isn't a chat schedule, so it's hard to know when people are around to chat. Also, the chatroom used to be inhabited by Greek Nationals...some of which were incredibly rude. Many people stopped trying to use the chatroom because of it.
Every once in a while, there'll be a post on the Chit Chat forum calling out for people to come chat...you can always check/post there if you wanna chat!
