I've applied this component on several sites and have worked very well. My favorite option is the choice to deliver what kind of subject you can set so it can be as flexible as possible to deliver certain kind of messages.
The small con y see on this extension is the limitation it has of adding 2 extra fields and not customize them for each language is implemented, thing than i have cheatd with a small trick on template override.
The componet is really easy o use but if you need to build something with more than 2 extra fields on the form you became limited on the form.
Thanks for your comment.
The Joomla 3 version has unlimited fields and multi language support !
Is easy to customize and suits very well to se it as a simple slideshow or a good way to make something diffeent to our site's background.
Like we say here is money well spent.
It is very intuitive even for the most inexperienced joomla user.
