#foreach

If you want to skip every other item, you'd need to do something like,

	#set( $isOdd = $velocityCount % 2 )
	#if( $isOdd )
		## ... Your code here
	#end

You could also use FisherMill, a tool for #foreach...
I didn't figure how to document it propely for addition in the tools 
project, so for now you can find it at:

http://www.chez.com/denisb/java

You could do:

#set ($wrappedlist = $mill.wrap($list))
#foreach ($item in $wrappedlist)
... Value of item is: $wrappedlist.more() ...
$wrappedlist.cont() ##skip one item
#end
