Great, yes It is not fit for my needs. Still a good product.
As it is open source,
you should make a github repo and invite contributors for the global translation module.
Yes, I could do that, but I could not support the users of e.g. a spanish version because my spanish is quite poor. This is why I settled for the german speaking market. That's Austria, Switzerland and Germany. Still enough money to earn :)
You really don't need to support any one. It is an OSS none can blame if you don't fix his issue. All you do is just invite him to contribute changes they want ;)
Think it like, I am an Indian and want this software in Hindi/Gujarati/Tamil.
What I will do is grab your global English file, Translate the appropriate part of strings to my choice of language and push those changes to your software.
which means user who are capable will support ecosystem.
