Are there any websites help me make friend with others for free?

Uhm.. Facebook? Tumblr?

craigslist.org has a “strictly platonic” relationship page under “Personals.”
There’s also meetup.com.
And Fluther.
Welcome to Fluther!

Meetup has worked out for me. You only need to pay if you want to create events. You can find ones around you’d like to go to and RSVP for free.

Craigslist. Facebook. Okcupid and Plenty of Fish.

Penpal.com is International.

Join some groups, either in real life or on internet (Facebook is an example).
