The point is that nobody was moderating the forum - or, in other words, moderators had 2 days off. Nobody was checking the messages for their content. Two days off a year don't seem too much by any working standards, I hope.
You could have appointed one or two temp mods.
As you have done similar before, it didn't take long to figure it out.
I was mystified as to how a poster and his [girl] friend were both on-line at the same time and no-one noticed. He got all the advice, she got none.
Your work is
appreciated. Happy New Year to the Admin team.
