Help:Signature
From Archiplanet
On talk pages, we recommend that all users sign their comments using the four-tilde (~~~~) wikimarkup code, which creates a linked user signature, including date and time:
Wikimarkup Resulting code Resulting display ~~~~[[User:Example|Example]] ([[User talk:Example|talk]]) 20:52, 27 May 2012 (UTC)Example (talk) 20:52, 27 May 2012 (UTC)
The three-tilde (~~~) option is also acceptable
