About the custom sprites thing, you could try to do something like what Sprites, Inc. has done. When they started their custom sprites part of the site, they made a sub-site just for customs and edits.

Of course I don't expect tSR to do this exactly like how Sprites, Inc. does it. But the idea could help keep rips and customs separate and easily findable.
