You can register your old sissyfighter name again (unless someone nabbed it while you weren't looking!) but you'll be starting over with zero points.  Once the hungry server gobbles your Brownie Points, they are gone for good.  Yipes!

When you register a sissyfighter name you need to complete at least one game with it in the first two weeks to make it offically active.  After that you'll need to complete at least one game in each three-month period to save your girl from being deleted due to inactivity.   To keep your name active in the message boards database you need to make at least one post in each three-month period.
