About us
BoardTracker.com, a Pidgin Technologies property, is an innovative forum search engine, message tracking and instant alerts system designed to provide relevant information quickly and efficiently while ensuring you never miss an important forum thread no matter where or when it is posted.
Boardtracker brings the most targeted audience closer to the boards, by being a search engine only for boards and by supplying a categorized and highly effective searching and browsing experience to users.
BoardTracker can be used in a number of ways..
# As a search engine in the 'traditional' sense. All the information in our database is from forum threads only, all extraneous text on a page is excluded by default which allows use to return even more relevant results without the 'spam'.
# You can pre-define search terms and preferences and BoardTracker will notify you in a number of ways (email, Jabber, Site) as soon as a thread matching your search term is posted on any of the thousands of forums we track.
# BoardTracker can be used by unregistered surfers and by registered free & premium accounts for additional useful features.
# Corporate users can arm their sales and marketing staff with BoardTracker accounts to give them essential business intelligence.
We are constantly adding new boards and forums and expanding our database to provide the best coverage possible. If you are a board owner and would like your board included please visit our Add a Board page.
Other Pidgin Technologies properties include Fotopages.com, a popular foto blogging site.
