I fully endorse this excellent suggestion ... At the motor show, I saw couple of persons wearing name tags ...
If it is not too much work, then the organizers may prepare the name tags .. but since the actual participants may differ from those who actually participate ... therefore, it might be better if a template is created and members should fill in their details and make their own name tags.
Ideally, all members should get their name tags, but considering the 100K plus membership, it would require considerable expense and effort ,,, so this idea of mine has "practicality issues"
