To enable the Race+Travel add-on, log in and navigate to /Cover. From here, you can see the quote to add the add-on and if it's active, cancel it.
You must be on Laka Complete to enable the add-on. If you are on Laka Core, you will need to upgrade to complete before you can enable the add-on.
The add-on cannot be enabled for Core.
