I've often had problems with the RS feedback system. Around one-fifth of the messages I've sent through it haven't gotten through. I always have to save my messages before I send them.
I've been reluctant to send messages through it for the past year and a half since I only receive replies from the people I sent them to 50 percent of the time. So I can't tell if the person received the message or if they're just ignoring it or forgot about it.
Kind of annoying when you can't even tell if the person received your message half of the time.
