Yes, yes I did. He wanted the Halo 3 emblem brush that someone made at some point in the past. Since I don't have it (or any Halo 3 brushes for that matter), I provided him with a link to a few possible alternatives, preceded by a rather scathing remark on the irony I found in the situation. Considering how easy it is to find and/or make brushes, I found it rather ridiculous that Fiend, who proclaims himself as one of the best artists on the site, didn't display the ability to recreate in any form that which he had lost. But apparently such a thing was construed as a post by a misinformed poster. Such a pity that no one appreciated irony anymore...
EDIT: Ah, emblem brushes. The word emblem didn't click in my mind. I present to you:
Google! First two or three links have what you're looking for. It's still very ironic that you couldn't do this yourself, though...
