Hi,
First, it seems that FGCom has now been providing good service for a while, so I wanted to thank you for that. ATC-pie has integrated the new binaries over a month ago so its users can now enjoy a non CPU greedy system, and the cool features like ATIS recording, which pilots can listen to before initial contact.
Second, and about ATIS messages, they seem never to be removed unless we record a blank message over them ourselves, whereas I thought they were meant to be deleted after 24 hours or so. So you can take this either as a report that the cron system is broken or as a feature suggestion.
A typical ATIS msg starts with a recorded time, which makes no sense if they can stick around for over 24 h.
