Calling people by their Real Life name in WoW

[Solzan Nemesis]

No matter what game I play. I am Sol. Its always the first three lattes of my main characters name. I like to keep secrets and one of them is my full name. First, middle, and last.

[Jun]

They just call me.... Chuck.

Too many Steves in the guild to begin with.

I call my fiancee by her name in voice chat. Other than that, we usually have nicknames for each other, or shortened versions of character names.
Even when we're on alts, we call each other by those nicknames, or by the main character they play with.
For the few that don't want to give names, we don't push or press. It's just something that kinda works out on its own.
