I have 5 autoblogs ticking away nicely. all targeted at the same keyword. I also have my main site targeted at the same keyword. My main site has a "download" page that uses Interspire Email Marketer form. When someone fills the form in, they get a PDF emailed to them. Now what I wanted to do is make all the 5 autoblogs have a "download" page that allows visiters to get the same PDF. I was going to use the same form as I do on my main site. If I did this, would there be a danger of google figuring this out? Does this help google know that all 6 sites are linked?
