My own prelaunch will be 5 days, but i'm not sure about launch. I was thinking with 7, but might go with 10.

I agree with Brian here, sometimes long prelaunches can really piss you off. I remember 1 article software came out 2 years ago and my mailbox was full of prelaunch emails.

And also it was funny to see 2-3 guys sending exactly the same emails.. ;D
