Bung, you've PM'd me, but set yourself not to be able to receive replies back so I can't reply!
In regards to your message, I'll like to dob in my compatriot Wheelbarrow01 who is far more able to assist with things if Fibre Landline. Thanks.
If you have Privacy set then you won't receive PMs or mention notifications. This is not new.
These links are referral codes
Geekzone broadband switch | Eletricity comparison and switch | Hatch investment (NZ$ 10 bonus if NZ$100 deposited within 30 days) | Sharesies | Mighty Ape | Backblaze | Amazon | My technology disclosure
So it looks like it won't underline/link it if the user has Privacy set. That makes it easy to tell at a glance whether the notification was sent.
Edit: freitasm snuck in :)
