[development] Module site_user_list is good, but..

Hi all, The module "site_user_list" is good, and fits my need. It can display users' profile, and can be searched. But I found a problem that if a field is set as "date", it will be displayed as a string, such as "a:3:{s:5:"month";s:1:"3";s:3:"day";s:2:"11";s:4:"year";s:4:"1992";}". How to change the string into normal format ? Thanks, Huisi
