EDIT: I added a bounty, if someone could help me figure out what I am doing wrong, its all yours.
Also, I don’t really care how this gets done. If there is a library that can help out, or something of that sort that would be great.
Since there is no Captcha involved, I should theoretically be able to log into Flickr and add a contact through code similar to the following…correct?
When I run this code and many many variants of it when I get to the place where I am supposed to submit a form to verify that I am adding a contact, it asks me to log in. Is the only thing this could be my failure to collect the right cookie?
I have IEHTTPHeader for IE to look at whats actually happening and I am trying my best to emulate it. I just can’t find where I am going wrong unless I just don’t understand something.
Flickr API can’t do this
All I want to do is login and add a predefined contact.

I’ve done something similar with perl’s WWW:Mechanize library, look into that.
