A while back I got an email from a person that wanted permission to use some content from my web site for a SkyWarn page. I didn't hesitate and gave permission to use the defined content.
Later I got another email from the same person and wanted to know if I would care to join. Seeing my data on the web site tipped the scale so I decided to join. A link to the application was sent. Red text on the page grabbed my attention and this is where the fees and BG check was required at my expense. I thought this whole thing is a scam so I left the page and never went back, but kept supplying the content.
After looking at the NOAA SkyWarn page (thanks jgillett), I wanted to figure out what is going on so I searched for the email again and found the link. After revisiting and looking the web site over, it's for another weather related organization... I should have read the complete page the first time.
