Joining is free and staying is free. There is no paid tier, no coins, and nothing you can buy your way into. Messages are free. Display ads in the member grid, under the member strip, and in a side column on a wide screen are what pay for the site.
What you can do here
Publish a profile with your age, gender, your city and country, and a photo of your face.
Search by place, city, age, a recent visit, or whether someone has a photo.
Pin a profile, see who opened yours, and write one to one.
Use a public room when you want a crowd instead of a private note.
