post star rating - add more letters to title

Hello,

I have a problem with post star rating, as the field to put the sentences in order to invite people to rate is too short, I miss 3 letters in order to write something correct...

I tried to modify it,
so I found in post-star-rating/psr.class.php
this :

ID bigint(20) unsigned NOT NULL default '0',

and also :

post bigint(20) unsigned NOT NULL default '0',

I changed 20 to 25, but no improvement. And this file is told to be desactivated.

What can I do ?
