Hi, I was trying to implement the task 1 and send the mail using gmail, but I got a reply that I can't use base64 encoding for my attachment. So I switched over to mutt to send the email [still using my gmail account] and send the mail again. I checked the email source and saw that It's not encoded. Content-Type: text/x-csrc; charset=us-ascii Content-Disposition: attachment; filename="task1.c" #include <linux/module.h> #include <linux/kernel.h> There has been no reply since. Not even telling me that I have done something wrong. I have waited for almost a day. Is there something wrong in the way I have gone about it, or is the dealy to be expected. Could someone, who has been successful in sending a result and getting a reply, summarize the methods they've used to submit a result [preferably using a gmail account and mutt]. Thanks, Ritesh Ranjan
