download a program to record it, there doesnt have to be a plug in made for every single thign that involves msn messenger when theres programs out there that to it. If it costs money, then buy it since you want it so bad...not everything in life is free.
i dont even think anyone will make it, unless someones trying to work on it secretly right now ah who knows...use trial programs for now...and if you GOOGLE you will find stuff you never knew existed, maybe even free software!
