you can allow other clients to see your shared files list, but i rather recommend you not to do it,. There are some (quite a lot, in fact) clients out there managed by the RIAA, MPAA and such which will try to get that list from you. Ok, you are probably not sharing any illegal stuff (we all hope you aren't, in fact) bt that's an attempt against your provacy, so it's disgusting.
