I must admit I agree completely with the email and PM system.
In my opinion, it is safer to make email and PM contact as there is traceability for one and secondly, you can get to know each other a little better prior to booking.
I check emails everyday or a least every second day and reply to each and every one. In fact, I say to clients, it is easier to get hold of me via pm or email as when the phone is busy it would be impossible to keep track of every call and text.
However, I have a laptop and roaming facilities and am also computer literate with a good command of the English language (what with being Irish lol) but the same cannot be said of all ladies working in Ireland.
Also even with email contact, I will request a phonecall to book an appointment as this is a safer way of booking as we all tend to go on gut feeling.
Hope this helps
