God, it's really not a problem if threads like this get bumped, surely? Someone has come on and searched for a subject they are interested in and wants to get the conversation going again.
If they didn't bump and old thread, most of them would start a new one. And then we'd have multiple threads on this subject just like we have hundreds of threads about smelly washing machines.
And if old threads are never to be bumped THEN WHY THE HELL DOES MUMSNET KEEP THEM ALL? EVERY SINGLE LAST ONE OF THEM, APART FROM CHAT?
Huh? That's what I want to know!
