Rubber Duckie is coming along nicely. This is an IRC client intended for those familiar with IRC and its commands. It's still in the construction stages, but is generally usable as a client now.
Currently available for download are the 0.4.0001 binaries and 0.4.0001 source. If you don't have MFC DLLs on your machine you'll also need to get this and unzip it to your Windows system32 directory.
Since there are almost no dialog boxes in Rubber Duckie yet (I'm still drooling over Bersirc's dialogs), you'll have to do most of the editing yourself in the duckie.ini and servers.ini files. This is not particularly limiting, because there's actually a lot of stuff you can change in the ini files. Go check it out.
