Please create the following namespaces on Sicilian Wikipedia:
CAT = Categoria = Category = Catigurìa (we proposed also "C" but seems not feasible - thanks Nemoralis)
T = Template
U = User = Utenti
DU => NS_USER_TALK
DP = Discussioni progetto
DW = Discussioni Wikipedia
I think the command to be added to the configuration file is:
$wgNamespaceAliases = array('CAT' => 14, 'T' => 10, 'DP' => 103, 'DW' => 5);
Consensus is in https://scn.wikipedia.org/wiki/Wikipedia:Circulu#creare_alias_redirect_namespace
**Benefits** (why should this be implemented?): typing and linguistical advantages
-----
For a new developer implementing this task, steps to add namespace aliases are documented [[ https://wikitech.wikimedia.org/wiki/Wikimedia_site_requests#Adding_or_changing_a_custom_namespace | here ]].
Expected outcome is documented here: T375979#10523898
