iortiz, I think your English has gotten a lot better since you've joined and you should take a lot of pride in it.
My only issue is that if someone asks you to clarify a post, you just say "it's clear to me." Instead of furthering the dialogue on here, that attitude just stifles it. People aren't always out to attack you, sometimes they'd just like you to expand upon the opinions you've provided. If you choose not to, it's your prerogative. However, just don't be upset if someone calls you out for not backing up your opinion.
