I have set up the chat feature on Sulkyland 7. Like everything else, it is fully compatible with Sulkyland 6, meaning you can chat with people using version 6 whilst you are on version 7. If you switch to another page to do something else and then return to a conversation, you will see what has been said whilst you were away.
I have also decided to remove code sales from Sulkyland 7, so the ‘Sulkyplus’ menu no longer exists. Classified ads (which are not yet fully developed) are now in the ‘Communicate’ menu. Code sales were rarely used and offered no protection against scams, so I believe that using classified ads and private messages is actually the most effective approach.
