Manual Placement With Short Code

I will like to manually place the code to your related post plugin. The place code is not the PHP version but usually starts and ends with [].

Do you have any thing like the above?

Secondly, I will like to increase the font size of the related post excerpt. The title font size works great.

Thanks
