Thanks, Liz.
The text on Help:Templates that I was (and still am) concerned about does provide pointers to existing templates. Specifically:
Project Boxes (Approved)
These are used to indicate that a profile is part of a project.
See Project Boxes for usage rules.
See Template:Project Box for instructions on creating them.
Research Note Boxes (Approved)
These draw attention to an important note about current genealogical research or WikiTree-specific work that's needed.
See Research Note Boxes for usage rules.
In this text, the two instances of the hyperlinked word "These" are hyperlinks to categories that contain the current collections of Project Boxes and Research Note Boxes. Those two instances of the word "These" and the two sentences that contain "These" are the only content in that text that is relevant to WikiTree members who aren't Leaders. (Because only Leaders can create templates, only Leaders can make use of information on usage rules and instructions for creating templates.)
Ideally, I think this passage should include the following text:
Under Project Box Templates (Approved):
Project Box templates are used to indicate that a profile is part of a project. See Category: Project Boxes for project box templates and guidance on how to use them on profiles."
Under Research Note Boxes (Approved):
Research Note Boxes draw attention to an important note about current genealogical research or WikiTree-specific work that's needed. See Category: Research Note Boxes for research note box templates and guidance on how to use them on profiles.
And since Leaders are the only members who can create templates, is it really necessary to warn that some templates in template categories cannot be considered officially recommended since any member can categorize any page?
