I presume there are non-English people on this forum. They might have problems with the language of the program. That's why it has already been translated in Nederlands (Dutch), Deutsch (German), Francais (French) and Chinese (!!).
If anyone wants to help or make his own translation, Mark Watkins has asked me, Arie Klerk, to be the focal point for translations. Send me a PM and I will give you all instructions.
Please help me find old threads where people offered to help translate SH? I remember a Swedish guy saying so, but can't find it anywhere... The same for Italian and Spanish. Maybe on other forums? NEED HELP! 
So I expect Sweden, Norway, Finland, Poland, Russia, Tsjech, Slovakia, Hungary, Portugal, Spain, Italy, Greece (did I forget any European language?) and of course the Rest of the World to have languages SleepyHead will be available in.
