We just want to use Sourcetree. Last month, we could sign up with an Atlassian account. This month, it is requiring a bitbucket account, which is not working for us. What do we need to do for about 20 employees (several already have an atlassian account) at Sam Houston State University to install and use SourceTree?
Welcome to the Atlassian Community.
The Atlassian ID option was removed as of release 3.0.8, so the only way to install it using an Atlassian ID is to download an older version of Sourcetree, register it and then you can upgrade to the latest version. You can find older versions in the download archive.
