Hello Harbi,

It is 'website'.
You can search for native English speakers on the left side of your homepage by clicking "language partners". You browse member's profiles and contact the ones you like through sending them messages or friend requests. You can also start instant chats by clicking "chat now" on any English speakers profile, they might answer and so you get in touch with them for further communication in the future.

The following are some tips to help you learn and improve your English in general:
To start learning English from the scratch you might need to take some initial classes to learn the alphabet , how to pronounce ,basic vocabulary and grammar. You can do that by taking classes in a language institute or by self learning online, although some guiding from a tutor at that early stage is recommended, unless you are able to depend only on audio/video facilities.
Then you have to practice and increase your vocabulary through different means such as :
*Reading at your level of comprehension simple texts or books and looking up new words .
* Listening to English through music and possibly reading the lyrics.
* Watching movies in English with subtitles in your mother tongue..
* Chatting with natives online using voice chats or in real life .Mingling with natives is a very good way to be constantly listening to speech in English, even if you don't understand at the beginning.

Make lists of words you learned and categorize them, e.g words you use at the office , words you use at school , greetings etc....
- Keep a diary in English . Try to use the new words you learned to write and compose simple sentences .The more you add up to your vocabulary, the more you can form intricate ones. Test your level!.
-Take a holiday abroad if you can afford in countries speaking English. It is an opportunity to practice with natives and learn more about the culture and people.You can sign up in language courses in those countries as well beside visiting its historical and monumental buildings and museums . You will be using guiding phrasebooks to help you get along there. The whole process will help you learn more words, expressions and practice speaking.
All the above can help you improve your language. Intensifying your efforts will make you improve faster. Concentrating on whatever method you are applying will guarantee you a more steady improvement.
