Possibly you hit another requirement apparently linked to the hinterland of findu.
Application done for my CWOP-identity => identity EW0725, followed by start of upload to CWOP, but due some other priorities was not able to complete registration for some time, for which you need to send an email to cwop-support@noaa.gov confirming that your site is located correctly on the findu.com map
When trying at later date, got the message that I had overrun their 90 day time-out for confirmation of registration, and that new registration required.
Nowhere mentioned that a 90 day time-out is applicable, but no flexibility .......
Result: upload to CWOP is running, but no transfer to their hinterland and not visible in station-listing, unless you know some trics.
