Premium version gives you access to Page Rank feature (and access to "good feeling" that you supported cool Slovak programmer :)). Page Rank is value in percent (%) for each website in the search result page, displayed as a progress bar. The higher the value, the more known (safe) the page is. More info about Page Rank value can be found here: www.domcop.com/openpagerank/what-is-openpagerank To activate your Premium features, create account (or login to your account) here: srp.fastaddons.com Thank you for supporting my work! Server renting cost is about 150€ per year so additional donations are very welcomed :)
