I don't see "three little dots in the bottom right of the posts," but I do see the word "Report" in the upper right of each post. Perhaps it depends on one's browser?
Anyhow, Lou, whichever you see, just click it on and make a report if you wish. I don't think HQ deletes harsh replies, however, unless they determine that it contains an attack. They will come in and remind people to be supportive in a "support" thread, but yours wasn't labeled as such, so idk.
As for the post you're talking about, Lou, I saw it and thought it was very rude and cruel. But like Bella, I also saw other posters call the mean poster out. Still, by all means, report it.
Even attacks - Often they deal with them, but sometimes they don't. Iv seen posts "disappear" here before when they had an attack in them. But I reported a post where someone called another person a nasty name and it's still standing.
Recommendations please, for a stopover on the way to Loch Tay
