Hello everyone!
I'm a Candidate Delegate for Brazil

and will be the delegate for at least 5 competitions here this year. I would certainly like to comment on most "bad points" made in the beginning of this thread, but I'm proud to notice it's no longer necessary. The community as a whole stepped up and the conversation is very mature (even the arguments against are more grounded now, which is nice).
Regarding language, you will certainly find enough people that are able to help you. I work in a software-building company and I have to communicate with Americans daily. Ok, that may not be the rule here, but last case scenario feel free to call me
The Spanish part is also true, from my point of view... if you know it, we will probably understand it, because most of the languages are similar, and non-native Spanish speakers talk slower than native speaker (that's when we have issues =P).
Maybe you will find someone knowing other languages, but in general you should stick with English/Spanish. Personally I don't know many people that talk French/German/Italian, and those are not cube-related.
I don't have anything to add right now =D but I wanted to present myself and let you know that doesn't matter where you come from, you will be well-received by us (or at least by me!). I really want to make friends all over the world!
If you have any question, just let me know. I will try to be active in this forum while we prepare for the WC!
Muito obrigado! (Thank you very much!)
