Unfortunately I couldn't make a Winamp skin for the second version without the program itself, although I'm sure someone should be able to convert it soon. If you are interested I just uploaded version 2 here [link]
Sure thing, your weather code for Sydney is ASXX0112. You need to paste that in the URL over the XXXXXXXX. Then you need to scroll down to the Meters section and replace where it says "Brisbane" with "Sydney".
As for the Network skin text being cut off, have you installed the correct font? The font is called Key's Comic 1 and can be found at dafont.com
