While looking for people to help me with making fixes to existing translations for Myth 2 (or new translations), I thought about something. Why don't you guys team up with other people. If there was a site with all languages, it might make it easier for portuguese myth players to find this place and have other people to play with.
The polish guys have a site which they seem to want to make available in all languages. The site is: http://www.soulblighter.net/
So far they only have it in english, polish, and dutch. Maybe you guys (if interested) could work together so that there is a portuguese version to that site and have these forums linked to that page so more people know about it.
