* You never want to Reply to the actual email.
As has been mentioned multiple times, this is actually a much bigger deal than the PTC Communities personalities seem willing to admit or address.
Another one is the cumbersome nature of using screen shots in comparison to simply copy/paste into an email.[1]
Another is to initiate a question in the first place due to work restrictions concerning web browsing.
Another one is get the full exchange in the email in case of those same restrictions.
These seem to be some of the bigger issues that get brushed aside by the "PTC Communities" community whenever this conversation flares up. Perhaps if this sort of stuff was addressed by now, the issue wouldn't be so prone to flare-up. (The realist in my then replies by noting that solving these does nothing to drive page hits to the web site.)
The rest of his post is standard forum stuff. Nothing really there to see except for people not used to forum software. So, important for some, no doubt, but not that much.
[1] While not speaking for anyone else, I can confirm I won't be taking screen shots, saving individual files to my workstation, uploading them to PTC, then posting them into a forum post. If they had some sort of copy/paste, like replying to an email does, I might have a different opinion.
