Forum notifications have been down, and I thought this thread was finished!
Anyway, use the search button to look for posts about how to remove LW. It could probably be done faster than waiting for someone to happen by and notice your post.
Basically--trash the LW folder in the Applications folder, and delete the LimeWire folder and files in the Home Library folder.
The search will probably reveal any more details as you think of them.
Cheers
