Oh Rosie you are preaching to the converted here - it really is a bugbear with GN. However, an irritation is those who don’t read the thread - a recent one was asking for birthday present suggestions for a grandson. After many ideas, the OP posted her decision, but additional posts came in, thick and fast afterwards.
It was another post, perhaps last year that annoyed me. A poster asking advice about her Mother, later posted on the same thread, that her Mum had died, but again further posts flooded in, one even wishing her good luck with her Mum’s situation!
I agree Sago that a thread may still be of interest, but if it’s from 2017, why not just start a new thread, using the same title.
I’ve long wondered if GNHQ could perhaps remove (and archive?) threads that are several years old and out of date?
