Pros: Match is a really well-established dating site, aimed at helping people start serious relationships and find love. If this is what you're looking for, you'll be able to find like-minded people on here. Cons: It's free to register and start using Match, but to read and send messages, you'll need to sign up for a paid subscription. Plenty Of Fish Changed: Started Charging Money & No Longer 100% Free. Recently in 2015, POF was acquired by new owners.Markus sold the company to Match Group, which is a massive company that owns a huge number of online dating sites, including OKCupid, Match.com, Tinder, Chemistry, OurTime, Meetic, SinglesNet, DateHookup and many other big name dating brands. Plenty of Fish, as its name suggests, features a wide selection of dating profiles. It is free, but you'll probably find it far easier to use if you pay for the premium services.
