2. POF (Plenty of Fish)
Plenty of Fish offers incredibly personalized services. Along with helping you find a match who is interested in the type of relationship you are looking for, it also suggests local places to meet up. One of my favorite features is that it allows you to see who has viewed your profile. You are able to set up your account so that certain people cannot contact you, which is a brilliant idea. If you are looking for a long-term relationship, anyone looking for a "hook-up" or casual relationship is unable to send you a message. Many people use their website, now you are able to take their fantastic service with you everywhere.
