This plugin is base module for sending email asynchronously. When sending a lot of mail from Q2A, you need to take many things into consideration. Especially, if e-mail is sent to many users in the event of Q2A, reaction of screen will worsen linearly. Since plugin is once saved in database, and transmits e-mail little by little later. Therefore, the reaction of screen does not worsen. Moreover, risk of receiving claim from server's administrator also decreases by sending many mails at once.
There is no user view in this plugin.

This plugin is not a thing guaranteeing the movement in every environment. If you install third party plugin and customize Q2A, plugin may not move definitely. Particularly, this plugin does not support external user at present. In addition, it may be necessary to hack program of this plugin when override function collides with other theme and plugin. This is not avoided in structure of Q2A. Anyway, please do not forget that this plugin was tested only in standard installation state of Q2A.
