I am happy to see answer to our question, even the answer doesn’t fit our hopes
In our University we have 4 common languages, for different public. These notifications are a problem for our users. When it’s an internationnal event, we let it in english, but for local event…
Maybe there should be a solution that doesn’t require a lot of ressources for the dev team :
1 - Withdraw the introducing english text from the template source (select and delete texte)
2 - Pre-filed the “messages” field with the current texts in the “Notifications for registrants” section (add html text in textarea field)
3 - if people want to replace it by their own, they just need to edit the “messages” field (WYSIWYG)
The only big deal are the placeholders (name, event name and event date)
You can withdraw the name because it is repeated later. The event name is already used before in title. Juste add the date field under the title and it’s done (edit html template file).
And the day you have the time to rebuild this indico’s feature, you can improve it we text editor including placeholder (like the mail editor for contacting registrants)
For you that should be a one small step for you, but a giant leap for all non-english users
Thanks for reading me !
