Hello, Elle!
I have came across "estop" before, probably in a crossword puzzle!
Think it is a legal term.
The best I can do regarding getting in touch with Mr Rogan is to give you Rose's email address at The Times.
That's who we dealt with before.
I think you got on very well with Rose, as I remember?
She runs Feedback at The Times.
The address is, feedback@thetimes.co.uk
Rose will likely pass your tidings on to Mr R, and he will respond to you, hopefully.
He usually does.
(He told me to get a map of the London Underground!)
You may tell Rose "hello" from me!
