Dear Sir or Madam,<br>We are students from Poznan University of Technology in 
Poland.We want to develop our GUI  enhancement for  OpenBSC project.It&#39;s
 about adding and deleting users registered in network. We have already 
implemented adding logged users, but we couldn&#39;t make this part of 
program, which is responsible for deleting users when they have already 
logged out. Could you give some advice, where to find appropriate place 
in the source code in OpenBSC.   <br>
Thanks in advance.<br>Best regards<br><font color="#888888">Marek Świąder</font>
