Forum:Username HTML

Hi,

I noticed on star wars wiki on some pages they have a template and it says Help me username etc. and I wander how do they get your username e.g: If I login it says "Help me Cap123" and If I go onto bot account it says "Help me Cap bot". Cap123 (Talk) 10:06, August 15, 2012 (UTC)
