Ive been doing that in every MMO since 99 in EQ , used to set up free exp rez and buff stations, hide magic armor, items etc on low lvl mobs for low lvls to kill and get, had scavenger hunts, Drunken lvl 1 Gnome races etc.
However this game has no guild tag system so people know who we are, and people really don`t need help doing anything as most of the content is designed to be trival solo. kinda lame really as it takes away the fun of helping when no one needs help doing anything.
Hopefully the next MMO will be more of a MMO and less of a solo game with tacked on co-op.
