Do you know some websites where it's possible to make language exchanges?

Check your question from 5 days ago for the answer.

What do you mean exactly by language exchanges? (I have the feeling “language exchanges” is an expression that doesn’t translate idiomatically into English. Do you mean a place to chat with others?)

The definition is explained by Wikipedia in detail.

I found this site.
The description of the site is as follows (copied from site) “Find a partner at the online community and practice your second language (any language) with a native speaker who is learning your language. We host your online practice with lesson plans, text chat rooms and more. ”

I tried it. To do that you must be Premium.

I found a few more that are 100% free, from what I can tell.

I got all these from a site that lists 17 free languange exchange sites. Some of them are for video chats, some are for text, some are both video and text.

@Zaku from what I can tell, a language exchange is a program that allows people to practice a second language. Some of the ones I found were English only, some were for any language.

A language exchange is when you speak a language the other person does know and you don’t and the other does the same.

Yes, that is what I explained. All the websites were saying that it’s a way to practice a language

MundoLingo.org hosts live language exchange events in several cities.

I’ve seen a Polish forum which had threads in both Polish and English and had a section set up for Polish/English language exchanges. I bet there are similar forums in other languages or countries. You could also put an ad on Craigslist or whatever site serves that purpose in the country you are interested in.
