Shouldn't we distinguish the global page (most of time in English, created for international audience = advanced level), from the local page? The local page matters most in this case: the goal is to have the user creating it. So I think the actual behavior of the module is correct.

@Trizek-WMF -- it sounds like you're saying we should be encouraging users with global user pages to create local ones. Is that considered a good practice? Is it common for people working in multiple languages?

I should also mention that I think it would probably be rare for someone with a global user page to be interacting with newcomer homepage. Right?

There is no good practice or formal rule concerning central pages.

We have that central user page because of Single User Login (see T16759: Make pages in User: namespace transparent to meta:User:).

The central user page exists to fill cases like the following - I think that they are the most common onces:

• people with an activity on central wikis (Commons, Wikidata) that would like to be known on another wiki. They could edit the wiki for some small changes (that's the case for photographers who disseminate their photos on wikis they don't speak the language.
• people who are involved in the Wikimedia movement and need/want to be identified on every wiki if their username is quotes
• people who just want to avoid a red link on their name because they go to another wiki than their usual one. For those ones, the central page can be in English (if they have an international audience) or in their primary language (because the page is displayed on that language wikis, where they are active on).

I don't think that newcomers would match those cases, except the last one; they can ask an experienced user about how to create an user page on another wiki though.

For what I've seen, I think you are right.

Ideally, we should have one central userpage where people can create translations or local implementations ("that page display on that list of wikis").

Thanks, @Trizek-WMF. Since it's unclear what the best decision is here, I'm going to move this task to "Revisit" and see if this comes up from community members.
