Template:Sigwrapper

Set this template as your signature in the preferences page. For example, setting the signature to:

{{subst:Sigwrapper|username|sigpage}}

Will result in the following being inserted as a signature

{{User:username/sigpage|date=03:23, 22 September 2024 (UTC)}}

The second, sigpage argument defaults to "signature", so if you have a signature template here, it will just work.
