Of course theres something that distinguishes your charecter from others. It\'s called your account name Fiere. =P Getting back to the other points though. I think my idea was misunderstood. My whole point, Wormtail, was that nothing should appear above your head for that exact reason. The idea I was countering in that post was the simple yes no abilities of the proposed introduction system. If you were to try to join a guild undercover, you obviously wouldn\'t want them to know your real name. The only way they wouldn\'t know your real name, would be if you declined the introduction feature. No one will trust anyone that declines to give out their real name. Ok. That\'s clarified.
Next, I still think that it\'s pointless to have someones race/sex shown above their head. If you can\'t tell what someone is, it means that either a) they don\'t want you to know, and they\'re covering themself up, or b) the devs did a poor job on charecter graphics. After seeing what they\'ve done so far though, I bet that the charecters are going to be detailed enough, so that you won\'t need their name/gender displayed.
I don\'t see how allowing people to tell different people different names would be a problem though. Anyone you trust(your guild members, friends, etc.) you would give your real name to. People that you don\'t trust, you could give a fake name. Maybe this could be a skill or something to prevent abuse. Maybe you have to give out your real name, but there\'s a skill, like lying or something, that allows you to give a fake name to someone. There could also be a skill to detect people that are lying, or truth spells. I dunno, I think cross-guild espianage, would be virtually impossible without fake names of some sort.
