Disable time out

I've found it so frustrating having to relog because SL has timed me out after I've got caught up with something outside of SL. I tried to get a solution using my trusty Google but failed. Then the knowlegable and ever-helpful Whimsy Winx dropped me a notecard with exactly what I needed. So I'd like to share this with you.

"Second Life will Time You Out, there are many anti-idle devices out there to keep you logged into Second Life, and hopefully you didn't pay for one, when there is a free lag free solution. These Anti-Idle device create "lag" which lose you and others down. If they have the option to be turned off, it still leaves the scripts running waiting to be turned back on.
To turn off idle timeout without the use of any scripts (in-world or out-world) do the following. Make sure you have the debug Client and Server menus available, you should see Client and Server next to Help if they are enabled.
If not hit Ctrl-Alt-Shift-D (Option-Ctrl-Shift-D for Mac users) to enable the Client and Server menus on your top tool bar and they will appear.
From the Client menu, choose Character. From the Character menu, choose Character Tests. From the Character Tests menu click on Go Away/AFK When Idle to remove the X next to it. You will never timeout from being idle now, this setting is persistent through logons."

Have fun!
