Hello Christopher, I just want to make sure you're aware of what you're getting into when you have an open join link out there for anyone to click. You have no control over who is clicking it, no way to prevent griefers from filling your chat logs with nonsense and/or vandalizing whichever map page the Player Ribbon is set to, and no way to tell who has been drawing on your maps. If you do kick someone the join link changes and requires you to edit your post with the new link. This is why we strongly discourage posting open join links. Instead, we encourage you to create a LFG listing , even if you do not enable that listing, and share the link to your listing. When someone posts to your LFG's Listing Discussion forum , in their post a big blue button will appear by their username and all a GM has to is click 'Invite to Game' and an invitation will be sent their way. If you want to stick with an open join link, just acknowledge that you understand the dangers involved and nothing more need be done or said. :)
