This template flags an article for the badly-needed attention of an expert or experts in the subject(s) specified (please use {{Expert needed talk}} on the talk page for non-urgent requests).
Anyone placing this statement must state why an expert is needed, by using either the |reason= or |talk= (to link to a talk page section) parameter. If you place this template without this, any editor may immediately remove it without explanation. Uses of this template with neither a |reason= or |talk= parameter are categorized in Category:Articles needing expert attention with no reason or talk parameter
When to use
Use this tag when you have identified a specific issue that requires help from a subject-matter expert (not a generally knowledgeable Wikipedia editor).
If you want help for most of the page, or if you want help soon, then try these much more effective options:
Leave a note on the talk page of any relevant WikiProjects.
The first unnamed parameter accepts the name of the WikiProject from Active WikiProjects
A second optional unnamed parameter, may be used to override the default "article" text with, for example, "section", "diagram" or "paragraph".
ex2–ex5: To add additional expert subjects, you can use these parameters to include more names of WikiProjects.
talk: If you have started a discussion on the article's talk page, you may link to that discussion with |talk=, using the section title of the discussion.
reason: You may use the |reason= parameter to provide a short explanation describing the issue directly within the template, instead of, or in addition to the talk parameter.
Add |talk=, |reason=, or both. Uses of this template with neither may be removed without further consideration.
date: The date of adding the template may be used as the next parameter, in the form of Month Year.
Examples
{{Expert needed|technology|documentation|talk=Section title goes here|reason=reason goes here|date=Month Year}}
{{Expert needed|technology|ex2=science|ex3=math|talk=Section title goes here|reason=reason goes here|date=Month Year}}
Follow up
When using this template, it is essential to provide an explanation using either the "reason" or the "talk" parameter. When adding a section on the talk page, you may use {{expert needed talk}} for this purpose. If the issue is of some urgency, you may also post a notice at the WikiProject that was included in the template.
