My family tree is about 4000 peoples , from about 6 countries. My problem is this:
I'm from Czech republic, my 3rd cousin is from Germany, what happend if I invite him via HOME / INVITE FAMILY. There I find my 3rd cousin from Germany, I send him a invite message, but in which language it will be? That i dont know.
It will be in german or in czech? It is very important, if it will be in czech , he will be not understand it.
So maybe it is time to put some icon or plain text to select language of invite message.
I have the same problem. I've sent an invitation to a person in the USA but the invitation was in Finnish and he couldn't understand it. There's also a possibility to choose the language on the site, but it doens't work. Your idea of choosing the invitation language is good and after getting the invitation a person could go to the site and choose the site language.
How it actually works is that it will send the invitation in the language of your interface.
If the person you are inviting already has an account open at MyHeritage, the invitation will be sent in the language of the interface that person has chosen.
We are aware that it would be better to choose the language if how the invitation it will be sent and we already reported that to our developers.
