Ah, this looks like the right place to announce this :-). I am working on a KDE lj client, since the current one (KLuJe) seems to have stopped development. Download from here, discuss here or reply to this post. Atm just login and post, but it does do custom friends posts, community posts, XMMS detection. Pls lmk what you all think. Next version should be out within the week, to include history editor and (possibly) tabbed simultaneous login.
Also, can anyone tell me what screened replies do? I have not put an option for this in my client yet as I don't know wtf it does!
