Hi,
The User tours additional plugin for Moodle 3.0 and 3.1 looks like a very promising plugin, likely to be included in Moodle 3.2 core.
The tours themselves can not be translated in AMOS.
I just made an illustrated step-by-step how-to documentation page about how to translate these tours at https://docs.moodle.org/dev/Translating_User_tours_from_Moodle.net . Please feel free to add or correct it as necessary.
The translated tours can be easily submitted to the Moodle user tours database.
There are already quite a few English language tours and some French and Spanish translations there
I guess that as soon as there are a few more translations available for (for example) the Dashboard, someone will be able to submit a multi-language enabled and configured user tour, that I think will be a very useful addition to many Moodle sites serving several languages simultaneously.
I would like to know what the other Moodle translators think about this new feature.
Thanks in advance for your feedback.
