Adhi, to change the content of the invitation emails go to admin panel>>settings>>languages>> search by "invite" keyword . Find needed phrase, and edit the content.

Hi Aliia, 
Yes, Found it. Thanks a million:)

Welcome )

Only Admins can invite new members or regular members/users can too? Where? (I couldn't find the link anywhere, sorry!)

Members can invite by using contact importer plugin

Quote from suresh kumar Members can invite by using contact importer plugin

Is that the only way? To be honest, I don't like to import contacts... those widgets tend to import ALL contacts and send out automatic messages. I HATE it when I get automatic invitations to Linkedin and other social sites from my contacts... 

Therefore, I don't want to impose this 'feature' on the users of my community either! :)

Isn't it possible to create another way to invite? Like a link somewhere that would send an email message to a specific email address, filled out by the member? 

That would be really great!

Evelyne, it is possible either by integrating already existing "invite a friend" plugin or by creating your own plugin from a skretch.

Would be great if you post this suggestion at UserVoice, since that is where ideas for the new Oxwall updates are chosen from.

Thanks again Aliia.

I have just purchased the existing plugin. It's very affordable and faster than developing my own... :)

Glad to hear that. Hope that all goes well.

I use Asian double byte language (chinese) and the invitation email show the Chinese text string in incorrect encoding. How can I fix this? Thanks
