A lot of dating sites that were free at one point are no longer free to use now; for example, Match and Lava Life.
Both sites let people browse ads for free, but they must pay if they want to respond to these ads or read and reply to messages they receive.
While using the site is free, it does require "credits" which you earn by logging in every day or by referring friends to the site.
All of the sites listed here are free to browse, to set up a profile, and to communicate with others via message or email -- whether you initiate the contact or the other person does.
The profiles on Mingle2 are pretty brief, but one advantage is that it allows you to search for people by interest.
These interests can be anything from spending time with your kids to engaging in interesting philosophical conversations.
Connecting Singles has some fun embellishments that make it a little different from other sites.
For example, you can play games, send virtual flowers and deliver e-cards to those you are interested in connecting with.
