Per my experience, I must disagree regarding response speed from Andrew/Small Green Computer. My most recent email question to him was on October 23rd this year. He responded within a few minutes. In looking at my various emails to him over time, he typically has responded same day or next day, with longest being 3 days.
I recently had an issue with emails not sending (did not involve Small Green Computer), but I was receiving email. I ended up restarting my computer and the issue resolved. Is it possible something may have disrupted your emails? I too have had response issues from some companies, so I can understand the frustration, but as I have indicated, that has not been my experience, including recently, with Andrew/Small Green Computer.
