You're being unclear again, and you didn't answer my original question
regarding blank tiles or whatever. In any event there's no need for anybody
with the site to be involved with your duplicate messages – you just click on
the three dots and select "Delete".
Right. That's why I haven't run into it. It would sorely tick me off. I'm slightly ticked off, even not having run into it personally. Not only does it suggest a waste of time that could be put to better use, but... oops, I forget the other thing, lol.
