Editor's Review of Plenty Of Fish
Plenty of fish has a huge member base, so you can expect to find a large amount of matches for your local potential dating partner search. With a free profile you can use most of Plenty of Fish's features; but they also offer a paid membership which lets you: view POF without ads, see if your emails were read, get higher placement in search results and more.
When signing up you can take the Plenty of Fish personality test. The test is 73 questions, seems long but it really does help as a chemistry predictor and helps you find your ideal match on the site.
When doing a search for potential dating partners, you'll definitely want to use the advanced search feature to narrow down your dating matches; as the sheer volume of matches can be overwhelming.
Overall, if you're looking for a free dating site, that has a large selection of members; Plenty of Fish is a good place to start.
