Fred's notebook entry: Jun 22, 2010

Hello, I'm Frederico from Brazil, but you must can call me Fred. I've just got in  joined italki.

I'm a Portuguese speaker and I've tried to learn English for a long time. to be honest. ('to be honest' does not add anything to the meaning - see http://www.urbandictionary.com/define.php?term=To%20be%20Honest)

Possibly:  I am a Portuguese speaker. To be candid, I have tried to learn English for some time now. 

So, I'd like to improve my English (skills - not needed) as much as possible because it's quite important for me and I really like that it as well.

Basically, I think the italki's friends might help me in my deal this. and I will be very glad if my English be is corrected by someone. Let's go!

Try to keep it simpler. Shorten the sentences where possible. Try to resist the temptation to 'add a bit more' to a sentence.  Perhaps try using fewer contractions in written English than spoken. Let the reader decide.

This is pretty good!  I tried to correct grammar in red.  The blue corrections and crossouts are just to make it sound more natural (although one would understand what you were saying).
