This is a great free version. Unlike other free form plugins, you can create as many forms as you like, but you will have to upgrade if you want to export the data. I've been using this plugin to capture data prior to downloading files. The user interface is not easy to work out and could do with a little more finesse but otherwise it works ok with the latest version of WP. I've yet to try out restyling the forms to make them look a bit nicer too. Generally, a great free plugin.
