Be careful, it's addictive. It starts with a simple "This is my first post" and soon enough you notice you are posting a 20k word essay on !onebag@wayfarershaven.eu why you think 40 litre bag is the most optimal on a 5 day trip.
Exactly, the thread would go on and on and someone would come in with calculations as to why you should instead have 15 litre bags if you have two bags.
In all seriousness I believe at some point it will be quite similar here :) give it time, the enthusiasts will figure out how to join and voice their opinion!
