Subdomain
The Subdomain field is a user-entered field that will become a critical part of accessing your Backtrace instance. After registration, you will sign into Backtrace by going to: https://[subdomain].sp.backtrace.io.
You can enter any value you want, with some limitations. For example, if you attempt to enter a value that's already in use by another user, then our system will reject it, and you will need to try a different value.
Tip: make one that's unique and easily memorable. For example, try using your company or project name.
