On my subscription page there is an option to log into an F5Data account to add those feeds to GR. After a couple emails between myself and Andrew Revering at Convective Development, Inc he informed me "The data feed that flows into AllisonHouse was a feature of our old product, F5Data. We no longer are selling subscriptions to that as we focus on our new web-based product F5Weather."
So that part of the subscription page might need to be updated to remove the link to F5Data since it is not a product anymore. Thanks.
