True, the replies to PMs sometimes don’t respond when you press reply/send. Oftentimes it take a minute or so before the reply will go through. And, if you go away from the page before the reply goes through, it is lost.
One other big frustration, and you would have thought I would have learned by now…. PMs from this site are usually delivered to my email address as well (gmail), which is fine. I spend several minutes typing a detailed reply, only to be told you can not reply here/via email, this happens after you type the lengthy response and hit reply from the personal email…
