well, i checked it out and bearshare was only sharing its own downloads folder, morpheous, on the other hand seemed to be sharing my whole local hard drive by default (i might be new at this file sharing stuff~but i know i didnot configure it to do that).
any one using morpheous, keep an eye out - i called all my friends who use it, no one else was sharing c: - but a couple of them were sharing c:\program files, crazy hey
