If I can make another suggestion, don't have your English skill as listed as high as it is on your italki profile. You say your English is poor yet you have it as four (or is it five? My eyesight is terrible) green bars which infers that your English ability is pretty good.  Also, fill out your profile with some information about yourself so if someone looks at it after getting a request, they might know something about the person who's wanting to chat with them.

Lyna, you only joined two days ago. You need to give it time.  Send messages to people also looking for language exchange, a language you both want to learn, or someone who is also looking to learn a language you speak.  Send a polite message of introduction about yourself.  Try to understand, some people are very busy, already have partners, or may be somewhat inactive on the site these days.  But please be patient.  Making friends doesn't always happen in a day. 

It's really interesting. Indicating English as your native language and saying at the same time that you have to use Google translator because of poor English is very strange.

Maybe it's the nasty profile picture that people don't like. It's a real mad looking girl in case you change it and someone wonders why I said this.
