The contact form plugin found in the WordPress CMS is a great place to start when dealing with form. The Contact Form plugin allows you to implement a feedback form to a web-page or a post in no time. It is an extremely easy form, that doesn’t require any additional settings, though there are some available options. All you need is just to activate the plugin and insert the short-code needed into the text. There is also a premium version of the plugin with more useful features available.
To install this plugin all one has to do is upload the Contact Form folder to the WordPress content/plugins directory. After that you activate it using the “plugins” menu on the WordPress admin panel. Once activated, there are plenty of variations to which you can apply to your new found form.
The only criteria I am using to base my investigative work would be the knowledge gained from using it first hand. I am not going to say that I am an expert on the subject of Content Managing Systems, but I feel that if one spends enough time figuring the ins-and-outs of a particular system, then they will make progress eventually. Another useful tip comes from reading other people’s reviews from WordPress/reviews and trying to recreate their progress.
