I have joined many photo and art communities from many countries and since I am Brazilian I have came across some Brazilians virtual forums too. In Brazilian communities I have experienced what I haven't experience abroad. People hates me essentially.
It happened to me be banned from the first one I joined. I am actually glad to be banned from that first Brazilian community because I founded later on many others came to the same situation. And the second one I tried I left when I realised my presence in there would not have a happy end.
After many months I moved and my life changed in a manner that I would spend more time in the internet. This is when I tried a third Brazilian community Mundo Fotografico and it is the first I am actually glad to be part of.
We are now planning to self-publish a book of Nature and Landscape photographs made from Mundo Fotografico members, which will also celebrates its 10th birthday this year. So I hope to introduce our book in a couple of Months from now. Until then, if you speak Portuguese I am sure you will be welcome in the community too.
