Welcome back to Maple!
Log in to your existing Maple account using the external account that you used when you first logged into Maple. Or, use a different account to create a new, separate Maple account from the one you already have.
If you have never logged into Maple before, click "Register" in the menu at the top of the page to set up an account.
You can login with any of these three methods, but remember to use the same option every time you access your Maple account.
