Apparently Tapatalk added a chat room feature. It's kinda cool, feel free to use it obviously, bear in mind though that it's not a feature moderators or admins of the site can help with. It's also a tapatalk only thing, so if someone isn't using tapatalk they won't see the messages. I guess think of it like a water cooler or smoking area at work, for "if you happen to be there" casual conversation.
