"I would love to use it, but I ain't about to email you from my work address"
Just as well. I did that, not using the registered email address, and later received a LinkedIn invite on the address I used from a, by then, former Register editor. AFAICS this was the only way in which the former editor could have obtained that particular address.
As LinkedIn had now got that address, and we know what grief that can cause, I had no option but to kill it (the address, unfortunately, there being no way to kill LinkedIn) and set up a new one in its place. An email about this to the present editor has never been answered.
So now I will not use the tips and corrections link.
