Microsoft is closing loads of its free, unmoderated chatrooms on Tuesday.
Chatrooms in the UK, Europe, Middle East, Latin America and most of Asia are all being shut to help keep you lot safer when you're surfing.
A number of children's charities said the decision was a good one when it was announced in September, but not everyone agrees.
Some fear children who can no longer use their fave Microsoft chatrooms will start using less safe ones instead.
