Feel free to use these icons as you like in any of your project, commercial or not. Some credit mention me somewhere is appreciated.
Yip always check the rights but if it is a problem I will remove them, in fact that maybe a good idea It will be done once I am back at the PC. oh and I always purchase any right when needed and donate to those that dont askI think what Sheldon is saying is do you have permission to redistribute these icons?
Edit: Looks like the designer gives full and free rights: http://raindropmemory.deviantart.com/art/down-to-earth-Iconset-328754834
