Upgraded a couple of days ago from Elyssa to Felicia - very nice. KDE4 will certainly need some using to, though.
However, when I wanted to play around a little with the desktop, adding themes/widget/wallpapers/plasmoids through KhotNewStuff didn't work - apparently it cannot reach the relevant server. Downloading directly from KDE-look.org and extracting in the relevant .kde folder does work, though.

There is probably something to tweek somewhere but I've no inkling where.
Any ideas, anyone? Thanks in advance...
