It's no wonder OkCupid is becoming the most popular dating site in the world - it's quick and it's free. You communicate with others instantly via private messages or chat.
But there's a clever catch. If you want to become an A-List member - and it's likely that you will - you will get extra filtering options and no advertising, but it costs between $5 and $10 a month.
If you don't like fat people, you can filter them out. There are 10 body choices starting at thin, average, a little extra, full figured, overweight and even a "used up" category for those who don't take body image very seriously.
And there's an all-important ego booster. If you receive high ratings, you will be notified by email that you are in the top half of OkCupid's most attractive users which entitles you to hook up with more attractive people.
OkCupid was originally launched under a different name by a group of Harvard University students. They call themselves "The best dating site on earth" and have an office here in Sydney.
