To permanently edit your tool order or change your animations, use the buttons in the bottom left corner. To spectate other users, you must have a forcefield. A place admin can provide this to you when they are present. Press R to rotate your trowel walls while holding the tool. Type "/classic [username]" to change your character to a classic-style version of the user you entered, with no bevels and the old head mesh. If the username isn't recognized, your avatar will be the default "old guest" avatar. If you want to go back to normal, type "/default". If you own a VIP server, type "/teambeacons" to toggle them on or off.
