Hi,
I received a notification by email and when I logged on, that I had been tagged. When I checked the message, it wasn't me that was tagged but Malc-c. I checked in the post and it was definitely @malc-c (https://www.ngaugeforum.co.uk/SMFN/index.php?action=profile;u=5722) in the original post. Maybe the algorithm needs to look at the first 6 letters not 4.
