Thank you very much for your great suggestions.
Now I have setup the translation environment on my mediawiki website.
I will try to working on the beta version. Currently I changed some Taiwan traditional expression into Chinese mainlan.
I am also a volunteer of Youversion too. They are using myGengo to translate. I think myGengo strings is a good and free tool. But it only support limited automatic import of strings, e.g., ini, php etc. I cannot treat your lng file as one of the supported file types. The best one should be ini format, but it use ";" instead of "#" for comments and does not support string name such as "vt.Header.Columns.(0).Text".
Nonetheless, I am working on translation of your new ChineseSimp.lng file with notepadd++ and update the wiki contents.
If you have some comments or suggestions please tell me.
