Wording as of February 27, 2011:

R2. Redirects from the article namespace,

to any other namespace except the Category:, Template:, Wikipedia:, Help: and Portal: namespaces. If the redirect was the result of a page move, consider waiting a day or two before deleting the redirect. See also Wikipedia:Cross-namespace redirects.

• {{db-r2}}, {{db-rediruser}}

Proposed wording per WT:CSD#SP:EF, SP:AF, and R2:

R2. Redirects from the article namespace,

to any other namespace except the Category:, Template:, Wikipedia:, Help: and Portal: namespaces, which are not shortcut redirects. If the redirect was the result of a page move, consider waiting a day or two before deleting the redirect. See also Wikipedia:Cross-namespace redirects.

• {{db-r2}}, {{db-rediruser}}
