I grovel at the feet of the lovely MNHQ and I worship the hunky techs.
I realise that a lot of the double postings occur when posters are using their phones and assume MNHQ is on the case to try and solve this.
Is this the same reason that some threads are posted twice? I find it a bit annoying (but assume it's not the poster's fault) and a bit confusing. Different people reply on the duplicated threads.
Do you have the facility (or can you create it if needs be) to merge duplicated threads into one thread? If so, how would we draw your attention to these? Report the OP in both?
I humbly await your reply.
