First, Thanks for your response.

I feel confident with my English. I don't feel bad when I don't know how to say something and I can't talk in almost situation. However, in the IT field (and in almost all professional fields) you have to speak properly to be considered an "expert". I'm not talking about having a different accent, I'm talking more about things like using the proper verbs tenses or the best sentence structure. This is what I want to point out when I refer to fluency.

Ahh, grammar & such! In that case, I'd actually say what you probably want is more input, and not output. Your brain should intuitively know what the correct tense and sentence structure is, and the only way it can learn that is by consuming VAST amounts of content in that language.

Then with a little attention, you'll start using the correct tenses and sentence structures as matter of course :)
