One important thing to knowIf you have used a plugin that instructed you to put some of the plugins code into your template or content, and you later decided to remove that plugin, your site may crash, showing up only a blank screen or half of the page missing! But don't panic, this can be repaired by just cleaning up the template.htm file from all of the plugins code. Its usually something starting with <?php
So keep that in mind, its a common mistake!
Your content is in not lost, and no matter what goes wrong with the plugins, your content.htm file with all your pages will still be there and recoverable.
