How can I do this?

[Jonatthu]

for example: http://localhost/foro/forumdisplay.php?fid=3

this is my settings:

function mn_freak_settings(){
return array(
'type' => 0,//0 = threads, 1 = posts
'fids' => '3',//Forum IDs applied for this plugin (separated by commas)
'gids' => '2,3,6',//Only these usergroups are allowed to be a freak (separated by commas)
'limit' => 5,//How many users should be displayed
'tlmt' => 0,//In hour(s). Only for threads/posts submitted in the last x hour(s). 0 = No limit.
'nlmt' => 0,//Only accept freak if their num of threads/posts in this forum is above this setting. 0 = No limit.
'avdim' => '50x50'//Maximum avatar dimensions (width x height)

);
}
