Help with recent post shortcode

I am playing with the shortcode for the recent post plug-in.

Here is what I have so far: http://cohort21.com/post-from-around-the-cohort-21-network/

To get that I played around with the following code.

[globalrecentposts number=”30″ title_characters=”60″ content_characters=”240″ title_content_divider title_link=”yes”  show_avatars=”yes”  avatar_size=”50″]

apparently there are more attributes that I can play with but I dont understand what they do.

‘number’ => 5,

‘title_characters’ => 250,

‘content_characters’ => 0,

‘title_content_divider’ => ”,

‘title_before’ => ”,

‘title_after’ => ”,

‘global_before’ => ‘

    ‘,

    ‘global_after’ => ‘

‘,

‘before’ => ‘

  • ‘,

    ‘after’ => ‘

  • ‘,

    ‘title_link’ => ‘yes’,

    ‘show_avatars’ => ‘no’,

    ‘avatar_size’ => 16,

    ‘posttype’ => ‘post’

    I want to make this page look cool.

    Can someone help me formate my short code so I can make this page a little more pleasant.

    some examples that I can cut and paste would be really helpful.
