Probably nothing new, because the technical details are already in the Wiki, but let me write it in human-readable form

So, let's suppose you've had enough of always 'OK'-ing your login after waiting for the SL login screen to come up then wait more. You can actually use command line parameters to ease logins by creating a batch file under windows, and you'll only have to wait once. (For the lazy ppl. like me

1. create an "sllogin.bat" text file under "c:\Program Files\SecondLife" (provided SL is here)
@echo off
cd "C:\Program Files\SecondLife"
SecondLife.exe -login Zonax Delorean myPasswordHere
cd "C:\Program Files\SecondLife"
SecondLife.exe -login Zonax Delorean myPasswordHere
(Of course fill it with your own username and password.)
2. you can make a shortcut of the batch file on the desktop by ALT+dragging it from the folder to the desktop
3. Just double click sllogin.bat on the desktop, and you're in!
NOTES:
* Remember, the file has to be ".bat" and NOT ".bat.txt"
* If anyone has access to your machine/desktop, this is NOT SECURE, so don't even try!!!
* When SL would want to download a new version, this will make it go silly - and you have to cancel it, and then log in the 'old way' so it gets the update
* If there are any Windows Gurus around, I'm open to all tips on improving this
