The RPGenesis Survival Guide for English Speakers:
While it might be a little overwhelming to be part of a community event where most people will be speaking in a very foreign language, let me reassure you that generally you will have zero problem communicating in English here. Tabletop Role-playing games are never translated in English in Portugal, so all of us have become considerably fluent in the language just from engaging in our favourite hobby.
Don't feel pushed away from interacting in topics or asking for help (all the organizers speak English, as do most of our participants). We have always wanted to open this little event beyond our borders.
And before you ask, no, you do not have to write this in Portuguese. You may obviously write in whatever language you prefer (we would recommend a language other people could read, as we definitely would like to read your game (still, an RPG completely written in Pig Latin would have its merits).
Finally, I will use this thread to post up translations of any important announcements or topics (and link back to the original). That way, you can read here what is going on, and then go to the thread to participate.
