We have a Discord server for this purpose. Discord is more powerful than a shoutbox and also allows voice chat. Additionally, it can be better utilized on mobile devices. You can access the Discord server by clicking on this link and associating your Discord account with your Kinmunity account.
While it is possible to hide a shoutbox and make it only available to members, whenever a Shoutbox is present on a forum, it tends to decrease posting activity. We feel our solution, to have a Discord server, meets the needs of anyone wishing to chat with other users.
