Just like an email account WordPress blogs are subjected to spam in the form of unrelated and unwanted comments from people trying to get a link to their site. These comments are usually written very generally so they look genuine on every site. I’ve rejected them all because they had nothing related to the subject of the post or this blog in general. I would love to receive comments about this site. However, please make sure that your comments clearly pertain to ham radio or the post/page your commenting on. Your specificity will help me separate your comment from spam.

Why isn’t the map form working?
The Ruby script that process the map configuration information given in the map form is very particular about what information it will accept. For example, if you enter a Maidenhead grid as fn31 instead of FN31, the program will not produce a map because the first two letters are supposed to be upper case. Similarly, the title will be rejected if it has non-printable or non-ASCII characters.
I wrote the program to be very strict about checking its inputs to ensure that people cannot cause the program to generate a hostile PDF. Rather than trying to identify and detect all the bad things a malicious person might enter to generate malicious output, I have instead tried to ensure that only safe characters are allowed in the input.
