Sng Auto buy in

I've just searched on google to see if there's a way you can auto register for a number of sit and gos at pokerstars and found on (dare I say it???) another forum a program called session lord. Has anybody any experience of using this software? If not does anyone know a way of registering for a set amount of sit n gos without having to open them all manually? I'd like to be able to register for 8 in a session without having to manually open the lobby everytime disrupting my play. I generally play the 45 or 90 men ones on Pokerstars and I think 8 would be enough for a session.
