Once I have posted an article I will only change incidental things like mispellings or bad grammar.  I might occasionally annotate an article to correct an important fact which might mislead someone who reads the article but not the comments. Any normal clarifications and corrections will be posted by me as a comment.

The idea of a blog is to have a dialogue. So if any Brazilians do not like what I say, want to correct wrong information or have something to add please join in. Use a false name and a fake email address if you like. I will not censor or edit any comments as long as they are not abusive.  And if any foreigners want to add something or ask a question please join in the fun.

This will be a very boring blog if it is just me telling you what I think. If anyone wants to write an article please send it to me and I will add it to the blog. If you want I will correct any language errors.
