Seems there ought to be a straight answer to an honest question without having to take it 'offline'. Can we delete teams, yes or no? Is there no FAQ with this answer? Why would I PM you for a simple feature/how to question?
You can hide teams, but there is no option to delete the teams you created. I checked your account and it looks like you have already hidden two teams in your account. Let us know if you have any questions or need assistance with, thank you.
