Martin, Thanks for your suggestions. I did searched something on GECOS, and I was directed again to /etc/passwd file which maintains user info in an OS. Could you elaborate the test process a bit please? I didn't get you clearly. The only point I could get is that server registration doesn't depend on nick / username. If it does in code then I should remove the dependency? Bernie, I have some questions, * you asked me about setting up a XS. I have a XO, a laptop and a router. I have this link too : <a href="http://wiki.laptop.org/go/XS_Installing_Software">http://wiki.laptop.org/go/XS_Installing_Software</a> :P. Am I on right direction for setting up a XS? * After setting up the XS, what should I check? 'cause you mentioned in the comment: 1. refusing the ":" character in the name input field of the first boot and About Me control panel. 2. converting each ":" to "_" when sending the registration to the schoolserver. 3. in idmgr, convert ":" to "_" as well. I think I have found the code for 1st one. 2nd I think I know where to look into (schoolserver.py). 3rd one, I have no clue :P Wish you could help me with above.
