I saw that this website has some Chat Commands...
... but they were taken from PL.
SL has more chat commands. When I did a "/?" I saw guild commands as well...briefly. The main problem I have with that help list is that you cannot see the whole list. I haven't been able to figure out how to scroll back in the chat text, only make the window show 1/3/6 lines.
Can someone please post the full set of chat commands?
