Again in the way

After a long time, I want to write again. I have been really busy, because during the Christmas period I had to work a lot. However, now I have more free time to spend surfing on the internet, so I'd like to practise my English with people who want to speak about films, sports, books, politics or whatever they want. I need to speak more because although I finished a three years English course I still need to improve this skill. I could help you with your Spanish. Cheers!

Hello!

 I changed the beginning to "A long time" as it is a more natural way to say that some time has passed. "A period of time" is also correct but I wanted to use that word later when referring to "Christmas period ". Personally I don't like using the same word repeatedly.

 I also rephrased your sentence about "Speaking more" because what I understand from this sentence it that this English skill is what you feel still needs work and you have spent a lot of time and effort learning.

After a period of time Eventually, I want to write again. I have been really busy, because in during Christmas time I had have to work a lot. However, now that I have more free time to spend surfing on the internet, so I'd like to practise practice my English with people who want to speak talk (*talk sounds better)about films, sports, books, politics or whatever they want. I need to speak English, because I finished a three years English course, and I need to improve it. I've studied English for three years and want to speak the language so I can improve it. I could also help you with your Spanish. Cheers!
