Opinions Needed: If you have an account old enough to have a first and last name, is it better to use that as your display name or select a display name instead?
depends on what kind of display name you use.. like for me i use my married name as display name... others use them for family RP.. or just for shits and giggles
I'd say it's just personal preference, neither is really better than the other.

I dont use a display name at all. My account name is the only one I use.
Thanks for all the replies. I wasn't sure how people viewed display names vs old style names. 
I change my display name almost every week, and i remember once i was Pamela Resident, it's fun.
Currently I just use my old name as my display name. I haven't saet one up yet.
