Listed standard features are only availible in a paid ‘Pro’ verson

On the list of features included in the description reads Main Contact Form plugin features are… File Upload Form.

I installed the plugin, got it to work and then went to add in an upload form and find this is not a part of this plugin but is a part of the Pro version which is not what is offered here on wordpress.org.

The plugin itself works well, it looks a little dated in design but is quite straightforward to use. If you need a contact form plugin for someone who needs a form builder front end then this may be of use, just be aware that several of the features listed are a part of a paid version and not what you are downloading here.
