Hi @bmcgonag, you’re right we probably need to add an email on team creation with instructions on how to use a team site. I’ve added a ticket here: https://mattermost.atlassian.net/browse/PL-24
After you create a team your team will be found at http://domain.com/teamname, and http://domain.com will continue to offer the ability to create new teams. This needs to be more clear.
