I uploaded my first two audio files last week and they still haven't appeared(or I din't know where to find them).. Whats going on??
did you complete the upload process by adding descriptions to your sounds?
Because if you do, you're then taken to the newly created page of your sound, accessible to you alone, with a warning that the sound hasn't been yet moderated, but it's there.
In case you didn't describe them, you can still do that from your profile:
click on the "Home" link in the top left link under the freesound logo, then click on "Describe your sounds"; you should see a list of sounds you uploaded but haven't been described yet.
