Well, I'm the type of person who is willing to help if I am able to do so.
To that end, I have spent several hours fixing errors and making other enhancements to the English language translation file.Marek, would you like to trade this file in exchange for a 30€ donation credit? I figure that's about 10-15€ per hour.
Being granted permanent access to the the beta site and the 64-bit versions will be helpful to me. I think the updated English translation file will be helpful to you and the FreeCommander community.
