Mark was the one who took control of this and he hasn't been active on the forums since 1/4
His Linkeden profile now states:
Product Manager
Vonage UK
April 2015 – Present (1 month)London, United Kingdom
However it also states:
Regional Director
Obihai Technology
January 2014 – Present (1 year 4 months)London, United Kingdom
I hope he hasn't left Obihai.
EDIT: What a shame, Mark has moved on to pastures new. I wish him all the best and I know for sure his input, advice and help on these forums will be missed.
