What i can do if i want to learn dutch fast?

The best way of course is by joining a group for learning Dutch, but this usually involves paying a fee. Another way is by buying some basic books and trying to learn it on your own. You can also use other sources such as www.uitzendinggemist.nl (you can watch Dutch tv shows on there)

The "Teach Yourself" series are quite good for self study. Try to find a native speaker locally to help you with pronunciation and maybe try to find a local evening course (or more intensive day course). Also, try and get reading as soon as possible, even if they're children's books!
Finally, your Dutch speaking friends here can always help you with any questions you may have!

First of all make sure you are acquainted with the typical Dutch sounds (and although this will complicate matters - you can also familiarize yourself with the typical Flemish sounds).

The best way to get to know things fast is to listen or watch news broadcasts, making sure first to have seen them in your own language so that you are familiar with the content.

And finally you can of course contact any of the Dutch speakers here to get information ;-)

Also, http://www.dutchgrammar.com/ is a very helpful site :]
