Application to automate form filling on 2 different websites

Looking to automate the process of creating free subdomains on 3 sites like yi.org. The application will need to log in and create the sub domains with provided keyword/ip/login information and output a txt file that lists the created sub domains. ## Deliverables Would like the application to log into each of the 2 following websites (with supplied account info taken from a local text file): [login to view URL] [login to view URL] Each of these sites offers free sub domains to multiple domains, [login to view URL] for example includes; [login to view URL], [login to view URL], [login to view URL] etc from drop down menu's on the sub domain creation form. What I would like to do is supply a list of keywords and IP's, and have the software create sub domains based on the supplied keywords for each domain on each service website. To finish I would like the software to output to a txt file the domains created.
