I would appreciate if there was an easy way to find my own sounds. It seems silly that I have to search for my own sounds or username to find it.
I already have my username in the top bar when logged in, so it would be an obvious (and easy?) choice to make that a link to my own profile. Most other sites do a similar thing, and I actually clicked it several times, simply because I expected it to be a link.
Underneath the Freesound logo click Home, that is your home page. You're not the first not to know, honest.
It would seem more consistent with other content sharing sites (dA, YT...) if clicking the username (top right, left of "Messages") would bring you to your /people/YOU page.
