Here are some tips (not enought to be a tut), like those that I posted on GL, for those who are unsure of the process.
Choose a custom font (it doesn't have to be white since we're only going to grab the shape) to use and make, or find, a semi-transparent/translucent image (png format perhaps) to work with.
Here I used my Chunky custom font (since it's white I have displayed it on a coloured background):

1. Open up the custom font and the image in Gimp and copy and paste your image into the custom font as a new layer.
2. Use Image>Fit Canvas to Layers to make all of the image visible and available to use.
I used a seamless pattern created by Lyle on Deviant Art.
3. Bring up the Custom Font Labels v1.07 Filter from the Filters menu.
4. Set the first two options (Create new characters and Clear contents) to ‘Yes’.
You can also set any of the following options to ‘Yes’ if required:
Remove all non-font layers
Ensure that all layers are positioned to the origin
Sort layers into order
Display current layer names in a message box
5. Click on ‘Ok’ and save the file under a new name (I will reference this as the background file).
Here is the result of my output.

6. Open up the original custom font again.
7. Now bring up the Custom Font Outlines v0.03 Filter from the Filters menu.
8. Decide what sort of outline effect you want to have – pattern, gradient or plain line – and set the appropriate options to ‘Yes’.
9. Set the outline width to whatever width you feel would look best with your custom font size.
10. Set the Outlines only layers to ‘Yes’ and click on ‘Ok’.
11. Save this file under another new name (I will reference this file as the outline file).
I used a rainbow gradient set to about 12 pixels wide as the outline border for mine.
