I was always under the assumption that my email id is visible to others until I talked to someone yesterday who mentioned that it used to be visible and now now it isn’t. I really don’t know what happened – I didnt change any settings from my side.
My email id is email@example.com. I have also added this id under “About“. Please feel free to email me if needed. Please note that I may not respond to each of your emails immediately but will eventually get to that – I am getting lots of emails per day – making things difficult!
