I have a "contact us" form on my web site located at [url removed, login to view] It is created using the cforms plugin for Wordpress. I am going to add a checkbox to this form that says "Keep in touch with us". When the user has the checkbox checked, I want them to be subscribed to my newsletter on aweber. All existing functionality in cforms must be maintained (logging to the database and e-mailing me the form results). The only extra behaviour is subscribing the user to the aweber mailing list. I believe cforms has a function to enable alternate processing. You may use this. Aweber must see the subscription request as coming from a web form. You can see the data that your script must post to aweber's system here: http://www.aweber.com/faq/questions/538/Can+I+Put+a+Signup+Form+on+My+Site+Without+Using+the+Web+Form+Tool%3F User should only be subscribed if they have the checkbox marked. You must clearly document your work! I expect the following documentation: - comments in code explaining what code is doing - installation guidance in separate text document ===================== Additional bid details: 1) Subscription to aweber list should happen in the background, transparent to user. No redirects to aweber thank you pages or anything like that. The user's experience should simply be that of a regular cforms process. 2) For more info from aweber see here: http://www.aweber.com/faq/questions/396/Can+I+Use+My+Own+Form%3F 3) Extended delivery timeframe to 4 days from bid acceptance. I am generally flexible with extending timeframes as long as I see progress.
