Maybe I missed it because I was concentrating on saving my family from Matthew, but how did I get on this list again, and what is it's purpose?
I've got one repeater that I am the trustee and coordinator for. The FRC has always been respectful and helpful, and while maybe not always the quickest, I found that they would follow through with what the said they would do. Besides that, a few of their board members have had some major health issues, so I treated them with the respect and patience we as amateur radio operators are known for.
