presentation

sorry for posting here, but i registered and i can't find the introduction forum (dumb). I have looked allover.
I think I will introduce myself here, and maybe help
someone if i can.
I i'm portuguese, and do some work with AC's and boylers and so on. I'm learning. my english is from watching tv(sorry for the gramar and the errors).
when i registered couldn't find the Introductions forum. So i started here.

Hi Duarte and welcome to the forum. :)

You have selected the right place to start.

Well your english is good enough for me and we hope that you can read it as well as write it.

"Bom dias" and a warm welcome to the site.
