Hi :) I guess it's not really relevant anymore but to upload to Nabble just try to use Nabble to post your reply but before you finish writing use the "More" button. The top option is to "upload file" and it places an html looking link into the message. You can edit the position of the link and add things before and after it but, obviously, editing inside the codign bracket can cause some quite strange effects. In Gnu&Linux Ctrl Alt and any of the function keys 1-4; F1, F2, F3 or F4 all do something a bit like Ctrl Alt Delete on almost all systems. Except that it's not quite so straight-forwards as forcing a reboot. If you have not done it before then you just use you regular login and then either sudo reboot or su reboot depending on which flavour of Gnu&Linux you are using.
