This is a SPAM - you need to sign up for a monthly plan to use this plugin. Plugins that require a payment should not be available through WordPress repository. A "trial" is misleading and certainly not in sync with the WordPress community. While I have no problem purchasing premium plugins, and have done so on several occasions, I do not trust dishonest people and the developers of this plugin fit that bill so well! If you need to "tease" people to try your plugin, then you also believe that your plugin cannot sell itself. DO NOT PURCHASE. DO NOT TEST. DO NOT INSTALL!
