Snippets missing that is to be used in the blog turtorial

Hi there,

I am trying to implement a simple blog for my site, and starting with the blog turtorial on the site.
In the install file it says that I should install the following snippets:

_{FlexSearchForm
PageTrail
DropMenu
NewsListing
UserComments}

But they are not to be found in the install folder on the original modX download (as said in the install) and I cant find them on the website either. Is it because the turtorial is outdated? Or how do I find the snippets?
Are there a mature blog template for modx that anyone can suggest?

Thanks a lot.

FlexSearchForm
PageTrail
DropMenu
NewsListing
UserComments

AjaxSearch
Breadcrumbs
Wayfinder
Ditto
Jot

I think that these would be the substitutes. All of these are part of the install if you select to install the default snippets. A good way to figure out the bloging method is to take apart the demo site (install with demo content).
