Hi there,
It's completely up to you if you choose to print your name at the end of your messages. If users have registered with a username other than that of their real name, they may want to print their name at the end of messages so that other users know their real name. But this is your decision! You can be as visible as you wish.
I always sign my name at the bottom of my posts, possibly more so out of habit than anything else!
Warm regards,
Cheryl, your editor
