To do that, just follow the instructions in the mail you will receive. Basically, you just hit the button 'Reply' in your mailprogram and send this reply. Here again it does not matter what text you may have in the mail itself or in the Subject line.
Every email ever sent to the list is archived here.
There is one archive folder for every month. This is the mainpage for all SuSE mailinglists, if you would like to know what else there is.
