whoops forgot to tell you guys
a great alternative/replacement/upgrade to sfxr
http://www.bfxr.net/you can give each other links that'll upload cool sounds you've made and it's like no hassle at all
for example clicking
this should load up a little harp noise i randomly generated when messing with it (warning, the links are tremendously huge)
there's basically a library of all your noise which is saved in browser cookies
but i recommend downloading the standalone version, which you can still paste links into, and is a lot more convenient to open and make noises with.
pst zay add this to the Useful Programs list!
