If you want to chat with other Wiktionary users, you may find some of them at #Wiktionary. Feel free to pop in and say hello; there is normally someone who will answer. If no-one does, it is probably because they are all away or asleep. Remember that everyone is in different timezones, so try again after a couple of hours.
In order to access these channels, you will need an IRC client. Some of the more popular ones are ChatZilla and mIRC, though there are many others. If you don't wish to install a client, then you can get to the channels through web.libera.chat
