Special Characters on sythe?

If anyone body used AIM, you could put in your profile or signature "%N". What this does is when another person see's your signature, it will replace "%N" with the username viewing it. It's like a special character and I was wondering if sythe has it?

Example :
Almond Joy's profile says :
%N is a member.

Sythe views my signature
"Sythe" is a member.

 

I've seen people do that with IP addresses. "Don't fuck with me your IP address is Blank"
