Cannot add custom invitation text, cannot preview the invitation email
The current invite feature is simple and straightforward, which should be a plus, but in our case, it means an annoying lack of functionality.
Most of our members don't like the hassle of clicking an 'accept' button and some don't really speak english. In old times, I used to add a custom text in our native language telling them what to do and give them my email for troubleshooting. Now I have to send a separate email to tell them what to do - but I can't be totally sure, since I can't see what the actual inviting email looks like... I'm pretty sure it's different from the one I received more than a decade ago.
I think adding two checkboxes below 'Add only to mailing list' titled 'Preview invitation' and 'Add custom text' would be a very nice solution which wouldn't compromise the current simplicity too much.
