Paulo...seja bem-vindo! It is super to welcome you to the Ethos Online Community. Please make yourself feel at home and have a good look around. There are a lot of resources and conversations about language teaching and ESOL teaching, as well as heaps that is useful for creating learning experiences for adults. It's also great that you are interested in OER.
I hope you feel comfortable jumping in with comments, suggestions, likes, and ratings...as well as a blog post at some point perhaps. Até mais, Hazel :-)
