I wanted to share this link that was shared with me for Brush Pilot. This is an app for organizing photoshop brushes. In addition to doing a great job of that, it can also convert .abr files to .png with transparent backgrounds. I thought some might find this useful when making and experimenting with brushes in ArtRage. With this link you can get Brush Pilot for $12.00, less than half the regular price. I personally used the link to buy the app and it worked fine. I should mention I believe this is a Mac only app.
