im not too far away mate, you should check out the central rsoc meet. there is one today.
for your siggy, go into your profile and go to the bottom. now for this bit you'll need to have your pics hosted on the web, somewhere like photobucket.com. then you paste the link to your pic into the signature box between [img] and [/img] and as if by magic your pic will appear as your siggy. hope that helps
matt
