Tonya aka "Oregonian" has created some easy-to-follow tutorials on how to create drop shadows for both text and graphics using GIMPShop
for Windows. The tutorials include instructions for how to do the same using GIMP
for Linux (in case you don't like the Photoshop-esqeness of GIMPShop
).You can read the tutorials here
Tonya promises more tutorials are on the way. Thanks Tonya!
