ProPlus is a search engine submission tool, which can post through an incredible 300 ports at a time (this number is limited only by your Internet connection speed). There are currently over 8850 Search Engines, Directories, Links Pages and Classified Ad Sites to which to submit your site within the SubZero Warrior Pro Plus's databases, but like the Warrior Pro, this is just the starting point. With the Warrior Pro Plus, you are also able to edit all existing databases, or add your own unlimited custom databases to this Submission Site Inventory. With the Warrior Pro Plus's built-in Links Page "Crawler", your computer and Internet connection will do all the work for you. The Crawler will "crawl" the web and automatically add multitudes of Links Pages, which are fresh and always up to date, to your Warrior Pro Plus's custom databases.
