CoolWebCraft: Absolutely free brushes with no credit links required

There are many free brushes available on the web. But most of them requires a "credit link" if you use it for commercial purpose. This sometimes becomes problematic, if i am using the brush for any commercial design and selling it to client /office boss, how can i ask them to put a credit link within the artwork.
So , I searched the net , mostly in devianart to find quality brushes where the brush creator does not insist to give credit link even if you used them in commercial purpose. hence these are absolutely free with "no credit links required" brushes (at least the time i checked them). To be sure , please check the terms of conditions yourself.

However, I would request that, if you are using them in commercial purposes , then be kind and help them popularize their brushes in some way like submitting the links to social bookmarking like stumbleupon, digg etc. , or in your community web site or any web site that you own. I think this is a very good way to express love to them for the for good work they have put together.
