I've had a small website for last 18 years and counting. Didn't get dot.com name until sometime early in the 2000's. But, as we got to know each other through posting, we eventually ended up having get togethers like this. Picnic in fall, and spring dinner at a resturant in May. We've had as few as 6 people and as many 50 at each of them. Ya never know.
Anyway, one of our friends from the site, (Judy), always got confused, between user names, and real names.
So she started bringing name tags, and making us wear them, with username and first name at least.
It got the job done, and was appreciated by all. Now she has the nickname of "Name Tag Lady". LOL
It a good idea to use. Especially at my age. I need all the help I can get remembering. <grin>
