I don't know how to change the name but that's alright with me! Add away!
Hello and welcome to PWN and URPG! I'll be happy to add you to the AIM and Skype chats for URPG (and PWN, if you want), but I thought you might want to know that both currently display (what I assume is) your real name. If you're okay with that, or after you change it, let me know and I'll do the adding. Have fun!
