Saw reference to this site (and GoldToken) on an ItsYourTurn users profile.
Generally I will make my move within 24 hours, but I have had computer problems in the past (and lost all the games I was playing while I was fixing the comp), so always err on the side of caution when setting game time limits - two weeks generally (also means I don't have to mess about with holiday settings unnecessarily).
(gem) Hvis du venter på din tur kan du klikke på "ændre" ved siden af "Opdater" på hovedsiden, sætte "Automatisk opdaterings-interval på hovedsiden og spilsiderne" til 30 sekunder. Så får du vist din tur hurtigere. (Servant) (vis alle tips)
