I just don't understand the auto responder. Could someone outline this for me??

(1) At which point does the autoresponder send emails?

(2) At which point should i contact the people, I have some now that show as having veiwed

(3) Are there any pre-written emails for first contact...etc

(4) I am a tad dissapointed as I have been at this for about a week and haven't had anyone sign   
up yet

(5) What percentage of a lead that cost me $3 each is going to sign up? I could go broke fast being a poor beggar

Thank you in advance for your support......Morgan

Could i put this on my web site...if so please send me the details
