I just purchased coffee cup software in order to make my own banners. ..only I can't seem to upload the finished banner on your site. It does mention FTP, but do you know anything about it?

If you purchase a standard web hosting account the typical method of transferring files to and from your computer is FTP. In the case of Class Creator our File Vault feature is the substitute for FTP. After making your banner you should be able to save it in the JPG format and upload it directly to your File Vault.
