The software is perfectly legal as far as I know.
It is a p2p program, similar to other p2p programs. The users decide what they want to share or download. LimeWire itself has no control over what users want to share, nor does this forum, which is separate from LimeWire.
Each individual user is responsible for the content they share, and would have to check there local or national laws to determine what is legal for them to share, as LimeWire is used internationaly.
