looking for an auto subscribe

[ianternet]

I am looking for an auto subscribe process where if someone leavea comment on my blog - their name and email gets automatically registered to my mailing list without interruption of the comments

I saw a good redirect script with VPM (viral profit machine) where it rewrites the information to my campaign and my mailing list such as aweber.

I would like to have the same concept with comments, as long as someone leaves a comment they are registered to my campaign.

also, I would like this to not have any interruption with my other comments issues.

I have seen so many email usbscribe for wordpress but not what I am looking for most of thema re strictly optins

has anyone found something similar? if not I may have to manipulate the VPM script with wordpress, which may take some time, since I am a rookie at PHP and SQL - but I learn fast
