It seems I've been an unintentional (/lazy/anti-social) lurker.
Last year, I purchased a Zyxel VMG-8924 off the back of information from these very forums. I genuinely thought I had registered an account on here back in 2015 but it seemed I managed to do it all from searching through existing posts. I even ended up searching for my "8924" to find any posts I might have made. To my surprise, I didn't find any recognisable aliases.
Anyway, many thanks to all of you and I shall try to post in future!
