Word Request: Email is Failing to Advance our Understanding

So, here is the situation: we are having a discussion over email, and the discussion is now exhibiting the following characteristics:

• It is getting nowhere.
• Everyone seems determined in their ways.
• We are pretty much talking over each other.
• It’s as if we are communicating over different wave lengths.

We need to recognize the situation, and put an end to this.

And therein lies my humble request: a word that someone responds with that identifies the situation and calls for continuing the discussion over another medium.

I’ve seen the pattern above so many times that I believe labeling it will help us all communicate better. Here are some wordy descriptions that may be used:

• Continuing this discussion over email is harmful.
• Continuing this discussion over email will cause more harm than good.
• This discussion thread has reached a point of negative return.
• We have reached a point where we should continue this discussion using a different medium.
• Email is not the best way to continue this discussion.
• Email is failing to communicate the point.
• Email is failing to advance our understanding.
• Email fails to advance the subject.

Yes, we can make an acronym, but down with acronyms. The world doesn’t need another EFAU, or EFAS. Let’s keep that as a last resort.

Any ideas?
