Looking at my plugins I found this plugin disabled. This is how it was installed, however when I opened it the descriptions says:

This plugin is required for EasyBlog Composer to working correctly.

Which gives me 3 questions:

1. Should I enable it?
   
2. What does it do? is it the parser for Composer syntax/code?
   
3. Do new default installations set this to on?
   

Thanks
