On what kind of designs you'd like to see created in the Design Labs, or what you'd like to wear. I know there are people out there who don't have the proper software to create some of the designs but are loaded with ideas. Mostly I've been submitting anime type accessories, but if you have a special request (and don't mind someone else submitting it for you and taking the T$ for it) send it my way. You'll be mentioned in the credits as the idea holder.
Or PM if you have questions about how to use photoshop, and if Paint.Net software doesn't install onto your computer because you don't have the latest Windows Service Package. You can download Adobe Photoshop 7.0 for free.
