@malgorithms is there any support to change usernames? Before teams, I had a company PGP key under the company name, but with this launch I can't create a team with the defacto company name since it's already in use.
I have the same problem.. The only obvious possible option is deleting the whole account, but even that says "If you delete your account, you can't get it back, and you can't create another account with the same name." so you might not be able to use it as a team after deleting.
