Create Profiles on 10,000 Sites, copy categpries and setup a welcome post

I have a list of 10,000 mainly forum and ning sites. I need four things done on these sites: 1) create a profile with details I provide for the profile 2) confirm the emails so the account profile is active 2) copy the list of categories 3) post a welcome post using the post details I provide I will provide the profile details using spintax (if you do not know what spintax is, don't worry - I will provide details). I expect the results to be entered into an online form I provide. The online form will also give you a place to note if the site is dead of impossible to signup on.
