At the intersection of Scrabble and Slackware lies ... WordBiz for Linux.
 

I plan to submit this to SBo once submissions reopen, but I figured I'd give LQ members a sneak preview.

WordBiz is the stand-alone app for connecting to the Internet Scrabble Club. Strictly speaking, this app is no longer necessary, because you can now play directly through ISC's web page. However, it still connects and works great. (Requires java.)

Free account registration is required to connect: isc.ro

Download the Linux ISC client here.

See README for more info. Enjoy.:)

Note: I had to leave out the sound update because this made the attachment too large for LQ.
