Never seen Blades or Loop outside a show/event but... regardless of the publication it does tend to prove you have to make it simple to access.
There is a tendency to want to build up a mailing list [they sell on well I understand] but if it gets in the way of customer satisfaction what is the point?
Mine [whether you like on-line mags or not] is free and easy at the point of supply, no doors, no name rank and number. Still works.
