A basic weatherTAP account allows a single user to be logged in at any given time, however, you may purchase additional "session tokens" to allow more than one user to be logged in to one account at the same time. When these are added, they are being added to the currently logged in account.

A basic weatherTAP account includes the complete set of lightning images on the web site as well as basic low-resolution, 10-minute old lightning data in RadarLab®. Optionally you may purchase real-time, high-resolution lighting data for RadarLab®. This optional service is priced based on coverage area and total number of logins allowed for your account.

Once you have added a real-time lightning package, you can change your coverage area by clicking on the "Real-Time Lightning Settings" link within RadarLab® Settings.
