I just installed them and, hurray, got them to work right away! I’d tried to install them a while ago, before WP 1.5 and miserably failed, but yeah, not one problem this time. Gotta love wordpress, it keeps getting better and better.
ETA: Also added the weather plugin to the currents. So you can see that we have crappy weather right now. 😛 I’m skimming through the plugin section at WordPress Codex right now, so I might add some more stuff.
