	* Check out the [List of All Known Available Custom Brushes](http://www.undermyhat.org/blog/2009/09/list-of-brushes-syntaxhighligher/),
	which includes many brushes that did not (yet) make it to the standard distribution.
	* Check [this wishlist](http://www.undermyhat.org/blog/2009/09/list-of-brushes-syntaxhighligher/#wishes),
	and vote for it, in case your brush is already wished for before.
	* You can request a brush for your favorite language at the [forums](/forums) or
	[vote for it](http://www.undermyhat.org/blog/2009/09/list-of-brushes-syntaxhighligher/#comments) (by adding
	a comment) on that same long list.
	* You can create a brush yourself, see this [handy custom brush guide](/SyntaxHighlighter/manual/brushes/custom.html). Once you do, it'd
	be nice to [hear from it on the forums](/forums) and/or submit it to
	the [long list](http://www.undermyhat.org/blog/2009/09/list-of-brushes-syntaxhighligher/) for others to use
	as well.
