Our new [Guidelines for Inadequately Referenced Answers](https://skeptics.meta.stackexchange.com/questions/1054/guidelines-for-inadequately-referenced-answers) include some suggestions:


> Welcome to Skeptics! Please [provide some references](https://skeptics.meta.stackexchange.com/q/5) to support your claims.

---

> Could you please [provide a reference](https://skeptics.meta.stackexchange.com/q/5) for your claim that the tallest ever person was 2.72m?

---

> I can't find in that source any evidence to directly support your claim that the tallest ever person was 2.72m. Could you please quote the relevant section or find another reference?

I prefer to customise my answers, but I do use the first one as a template with the [AutoReviewComments](https://gist.github.com/842025) userscript as a basis, or when I am being <strike>lazy</strike> efficient. It adds the "Welcome to Skeptics!" prelude only if the user is new (by some arbitrary rule).
