Not sure I follow what you're not seeing. When you download the module you should extract it then place the extracted folder (ensure it is called 'userforms') in your sites directory. It should be at the same level in the folder hierarchy as the sapphire and cms folders.
The SilverStripe version I have downloaded (2.4.4), has the following main folders: assets, cms, googlesitermaps, mysite, sapphire, themes.
But it hasn´t the path: sapphire/cms/jsparty to install the user form module in it. For example: sapphire/cms/jsparty/userforms-v0.3.0
Maybe the problem is that I dont understand the following instalation line: Place this directory in your sites root directory. This is the one with sapphire/cms/jsparty in it I am Spanish, and my English is not very fluent.
Sorry for the confusion when it said sapphire/cms it meant sapphire, cms - 2 different folders. If you look at SilverStripe install you should have a 'sapphire' directory. At the same level you should have a 'cms' dir. The 'userforms' dir should go there.
