This is technically correct however, I recommend extreme caution
Just because you can do something, it does not mean you should. People head to forums cause they want to interact with people. If you transform your forum into a different space where all human and robot content is mish-mashed together you have a high chance of destroying your online space. Whatever is done here needs to be done extremely deliberately and carefully.
We chose the whisper route on meta cause it saves us a bit of time when triaging responses, it does not replace us and has minimal and properly decorated bleed through into content on the forum.
@sam I could not see it though. Sorry. Also, I think I would need to install this plugin to make this happen, If I understand this correctly.
I agree, the idea on this is to be VERY personable and ONLY on some categories that people have FAQs etc… would be exrtemely helpful to respond automatically and in a relevant and contextual way.
