I want to change my infame Name because i want to upgrade to the highest Tier and started hating the numbers in my Name. So i want to change it to akronymus now.

Once you purchase the highest level, you can set the desired name on your profile page (of the main site). So your username is independent of the in-game 'thank you' name (although you may still want the name change if you want your in-game recognition linked to your forum name )
