Create sandbox version of Module:User

New page

--[=[
-- This module implements {{user}}. {{user}} is a high-use template, sometimes
-- with thousands of transclusions on a page. This module optimises the
-- template's performance by reducing the number of parameters called from
-- wikitext, while still allowing all the features provided by
-- [[Module:UserLinks]]. It is about twice as fast as the version of {{user}}
-- that called the {{user-multi}} template from wikitext.
