as we know wordpress comments requires name and email, I want to know if this can be forwarded to a script which it will rewrite to another form (optin forms)

it is similar to the viral profit machine divert script where it grabs the users email rewrites it to the subscription campaign and then to your list, but I would like to know if it can work with other plugins as well, such as the comment ajax.

I know its a matter of php and sql, I know a little of php, but not a enough to do what I want. also I just started using wordpress as well so i do not know the whole backbone of it.

in the end I simply want readers who leave a comment on my blog to be automatically subscribed to my optin, without any interruption of other plugins that maybe used for the comments

thanks - so far I havent found a plugin that does this
