The first clan I joined when switching to WWP was eN, with Wurzel as leader. I think we had IrwlZ and Pitchblack as members, can't remember the rest.
Reddeath was also ToP, Novicane and/or Vantage too, The Sherriff and BigC or something. Basically it was an allstar team of that era current best wormers. I also recall Griffix on the roster on ToP... but it was at a later stage I think.
Btw, what was the name of Tjerps brother? Never figured out after he became inactive.
