I have been learning English since I was 10. I really love this language and I believe it's very important nowadays.

We use the present perfect 'have been' when we use 'since' to indicate an action that started in the past and continues into the present.

Rememer to use capital letters for proper nouns, 'English' and a full stop is more appropriate here after 10.

'I' is a pronoun, however we always write 'I' with a capital letter. The word 'its' is one word in itself, a possesive pronoun. However, 'it's' is composed of two words, it, and is. Therefore in this case you need to use the apostrophy to indicate that you are using the contacted from of the pronoun 'it' and the verb 'to be' or 'is' in the prsent form of the 3rd person singular.

Nowadays' is more appropriate than 'now' in this case as 'now' means right this second and 'nowadays' means in this period of time for example in 2012. 

I really like to meet new people, see new cultures and have my own foreign freinds who I would like to meet one day, that would be a lot of fun. 

Capital letter for 'I' and I'm sure you know how 'people' is written. I have put a commar after people as you are listing three things that you like, before the last thing in the list you need to put, 'and'. We use who at the start of the sobordinate clause to give extra information about 'foreign friends'. 'Would like to' indicates somthing that you want to do in the future.

Just skype me or send me an e-mail and let's get to know more about each other,

what do you say?

The word skype in this sentence is used like a verb and so we need to add the conjuction 'and' and use the verb 'send' when we talk about e-mails. In English the word 'let's' with an appostrophy is the contraction of two words; the verb 'let' and the pronoun 'us'. 'Each other' are two seprate words and in this case, 'what do you say?' fits better than 'how about that?'. Remeber to put a question mark (?) after questions.

I hope that wasn't too confusing!
