If you receive a message from someone via POF you may want to check out their page on POF so you can know more about them. Here is a quick and easy method.
Unfortunately POF has now removed the Search > Username feature so you cannot search for a Username on the site.
However, there’s a way around this problem.
Just go to the Google search engine and type:
Replace USERNAME with their username
Their profile should appear in the search results, assuming their POF account isn’t too recent and Google has indexed their profile page.
