Sometimes you just want to get rid of stuff in a theme but you don’t have the skill or capability to edit it’s source code. Maybe because you don’t have access to it, or because you don’t want to risk your modifications being destroyed in future updates.
The Vanish plugin lets you specify CSS-selectors of elements to be hidden in your theme. A style block is inserted in <code><head></code> which hides all matching elements from view. They are still present in the source code, they will just be invisible.

eTemplates simplifies the creation and delivery of dynamic emails. The plugin is best used in conjunction with custom coded application style websites that send out emails populated with dynamic data to users at specific points in the application logic.
Some examples of usage could be:
<ul>
<li>Shopping carts</li>
<li>Social media sites</li>
<li>Project management systems</li>
<li>Your custom application here!</li>
</ul>
Use eTemplates to create consistently branded emails with ease!
