Instead of posting a full stop or the word placemarking?
I have seen a few posts over the last few days where a story is unfolding and I understand that people want to follow it and get updates and a conclusion (hopefully a happy one), but I think it is a bit insensitive for that to be your only contribution to the thread in order to placemark.
The op is most likely looking for support and/or advice and you just want to see what happens. That's fine but just watch the thread and lurk.
