Are you new to the game?
Need a little help getting your capital raised so that you can start uploading and creating? Or maybe you just want to buy a new outfit but just dont have enough starting cash?
The easiest way to make money is by camping. Camping is basically when you commit your avatar to staying on someones property to inflate their occupancy and traffic statistics. Many places in game have camping objects, such as camping chairs. These are scripted so that if you right click on the object a menu will pop up that has camp (or sit or another command similar) that will place you in position in the chair for example and the hover text will now read "#L earned".
Some places have dance pads that work just like camping chairs only instead of sitting there doing nothing your avatar will dance while you earn your Linden dollars.
Other places use a time clock. To use these you clock in, and have to stay on property, usually within a certain distance of clock.
Just remember when your done to clock out, or stand up, to stop the camping interaction. If you fail to do so your avatar will most likely be stuck in the animation (fixed by logging in and out) and may not be paid properly. If your game crashes, you are logged out for inactivity, or you teleport to another location without cashing out you may loose all of the money you made in that camping session.
