Hi Gerry,
You're absolutely right. Without history with members it could be hard to know how something was meant and someone might misinterpret. I can see how a comment as neutral as "off topic" could potentially come off as abrupt depending on where someone was emotionally, though presumably it is meant respectfully and is sometimes necessary. I personally wouldn't feel offended but rather somewhat guilty getting a note of re-direction like that. I always try to be mindful of not hijacking someone's thread which happens sometimes. (Often with good reason such as an embedded new member intro) but nonetheless...
It's nice having you back btw....
