Cellufun announced their 'Hellofun' celebration; a community event where users can decorate their homepages and dress up their avatars in costumes. Just like all people who trick-or-treat every Halloween across the VS, Cellufun users can collect treats and give out tricks, right from their mobile phone. Registered users will find -from today on- a link on their homepage that invites them to "Celebrate Hellofun." Users start decorating their homepages with Halloween imagery, choose frightfully clever costumes for their avatars, and compete in giving and getting tricks and treats.
