The glowy writing was separately done in blender as three different images then faded over each other. But I wished I could've done this in Blender too since that would look better but I have to get it done quick so I settled for the easier way. ^_^
But you can do it in Blender by using Composite Nodes, thereby overlaying another render layer that will be blurred and using a Mix node to overlay the original (unblurred) one with the glow render.
