Commercail/Non-Commercial Use  === yes a must

Credit Required === iffy I think this one depends on what one is uploading

like  example an object that person may want credit, some like myself who do poses and expression  we ask for it but it is not required.

Link Back Required  ===iffy  again same thing depends on the item being uploaded

No Redistribution  ===up to the uploader again depending on what is being uploaded to some people this is a must and I support their wishes, some don't even list a read me file.

Some people do want credit and that is fine but not all of us do,however all are a  good thing to have  some people will use them some don't care they just want to share with no hassle. Is there a way all these can be listed??
