Well, not exactly Free, You'll have to earn it.
Is English Your second language? Can You use an HTML editor? Are You fluent enough with English to translate the help file for ConBuilder?
If You can answer Yes to all of these, and get the translation done, then I will give You a copy of the latest version. I need somebody who can do the following languages.
Danish, Dutch, French and others. There are also 3 other files that will need to be translated as well. However, the translation must be done first before You get Your copy of ConBuilder. PM or E-mail me if So.
