Today is the best time for new Language, learners. Of course, I mean today Internet technology. Learning of course, has to make the big effort for it. Of course if you know 2-3 languages to learn another must be easier, also language are categorized by difficulty
http://en.wikibooks.org/wiki/Language_Learning_Difficulty_for_English_Speakers.
I write this as a Russian learner, for my blog. I choose Russian as, the language has/use 20% of Greek and English words (eg robot=робот=ροπότ). Also Russian is an important language for science and technology. According to a recent study, the number of publications in the sciences is highest for English, with Russian second (link).

The major teaching communication (with distance teacher) tool I use is the free Skype Internet messager [www.skype.com], of course you may use similar free chat/messager tools like GoogleTalk, MSN, …etc but you must use identical tool with teacher. With Skype you may have teacher to student or, teacher to students (group talk), free voice/text/video chat or even screen sharing (Skype 5). With Skype you may also send files to your talking partner… Email client programs also are used widely for communication and homework submit.

You can find a teacher easily online using special websites like
http://language-school-teachers.com and http://skype-language.com/. Here you register free as a teacher or as a student saying the languages you speak and the current interested language to learn. Teachers then look for you, or you(as student) may search/browse for teachers by the language they teach, country they are located, and so on. If you want group lessons which I do not like (by one to one talking you gain more and teacher has to do only with you, although cost is bigger in this case, not as in a group which cost is shared) you may find friends locally or classmates or friends online (facebook,…etc) to learn with you.

Surely exist online websites offering ready online classes with students from around the world, not have to setup yourself the environment…
www.mgu-russian.com/programms/online-russian-course/en
www.primelanguageservices.com
(these also offer one to one Lessons).
Of course, exist for other languages identical Sites, just search for “skype online french lessons” or search the language-school-teachers.com or similar site.

Considering the vast number of sites available today, there is more than enough good information to learn/read about grammar, most common words/verbs, starter points in a language,…etc, in text, voice, or video sometimes, and also quizzes, exercises to practice on, all is free. Also you may find online, some complete ebooks in PDF format, I found 7 in “Learn Russian” (in English) but not all in beginning level. Ebooks are paperbacks in electronic format.

As of real paperback books, there are teach yourself materials or teacher assistance materials for any language online, just search your online bookstore or google eg. “teach yourself Russian books”, or “Learn French books”. You may also find story books (eg novels or short stories) in your target language or search for books in a bookstore in that country language is spoken eg in a Russian bookstore if you look for Russian books, where also you may find all kind of books, from science to technical to social science and so on. If you have difficulty with the language you may try Google Translate to translate whole page to eg Russian->English, also if you click a link next page translated automatically. You may also request from a friend or teacher search a book for you or, even send you some books… The latter may be required for your language studies.

Online also you will find free access to online live or on demand, radio or TV station programs, just search eg “Russian online radio stations”, or any other language. Of course, you must pass the beginner level for this. There are also online newspapers and magazines in any field in your target language, just always search eg. “Russian newspapers”. Sometimes preferred find a website with a list of all newspapers by country like
www.world-newspapers.com. Same applies to magazines/journals although they may be listed together along with newspapers sometimes. You may also like this for Russian http://onejournal.ru/.

As you know on the Internet you can find almost anything, so here is some Learn a language Tips guides

At end, if you have questions and need answer but you do not know where get it, you may post your question in a forum of your target language, just search Google “Russian language forum” register/confirm-Your-Email and post it to appropriate category. Just remember choose “email me upon reply” or you may have to return in forum/myPosts to check for a reply manually.
