The password should not be the one you use for submitwolf, FTP or email. Simply make one up. However, you should note it down in case you need to change a listing at any given site that requires it. Standard is not. Enterprise can do batch submission.
Enterprise can read in form data.
Enterprise submissions do not get any email from us. Enterprise has customizable reporting to display your name and logo on the reports. Your site will be reviewed and if it is acceptable it will be added to SubmitWolf. Of course if you have joined the partner program and added a link to your add URL page, then it will increase your chances of being added. Often this can be solved by checking with your ISP or network administrator regarding what the proxy settings should be.
