Can we re-upload our older pieces?

Can we search out our older pieces?..  Should we re-upload?.. or leave where they are?..   Or can there be a composer section and his/her pieces he has contributed over the years?

I sometimes refer people here to listen to my work..  Is there an easy way to find it, 

Congratulations on the monumental task you've undertaken to update the site.. 

I don't think anyone is forbidding us to re-upload music. A few of us (including me) have already re-posted some previously uploaded work. The older posts are still accessible in the archives though and I personally won't be uploading any more old compositions unless they're significantly revised versions. I don't see a problem with putting up older works though, as long as we don't spam the site with a re-uploading streak. That might annoy some folks.
