<div style="width:65%"><small><small>{{welcome|Joker|sig=from Batman}}</small></small></div>

<nowiki><div style="width:65%"><small><small>{{welcome|Joker|sig=from Batman}}</small></small></div></nowiki>

You can assume that if no default is shown for a parameter that is not required, the result will be blank (i.e. in this case, the welcome message would not show who it was from).

To supply a value to a '''named parameters''', put the parameter name followed by an equals sign (=) followed by whatever you want that to be.  In the example above, this is {{tt|<nowiki>sig=~~~~</nowiki>}}.

Parameters shown with numbers are the '''un-named parameters'''.  You ''can'' treat them as named parameters, by typing {{tt|1=1=''your text''}}, but this is not necessary, except in the case that you want your text to include an equals sign (=).  Normally you just supply the value, such as {{tt|YourUserName}}.
