Hi everyone!
Would you like to exchange postcards with me? You can use your native language, the one you use in your country, with an English translation. It is very important for me that you write in you own language because there are so many beautiful and interesting foreign languages in the world, and all of them has have their own unique writing systems. It will be easy to please me, just send me your favourite postcards and everything that's in your way [I don't know what you mean here]*! :) I don't want to bound  limit** anybody with the postcard choice. There are so many interesting and new things happening in the world, after all, that I'm afraid to miss the moment! And one more little thing! Please put your name and the date on the postcard[,] when you're at the post office. That's all! Good luck to you and your relatives!
If you take part in the direct exchange, don't forget to sign the postcard (swap, name, country), please, so that I can thank you!
*in your way / close at hand? (meaning: everything that you can find close to you, that you already have, don't need to get somewhere)____
**not sure about this word. confine/ limit? can't choose.
