Looking at the forms page, which you can reach by clicking the word Forms on the top of the page, there are some new publicity materials you can download and use.
The two newest items are PowerPoint slides, one for standard size and another for widescreen.
You will also find there:
Participating Church Agreement to reserve slots
Two forms of registration tools
Color brochures you can print yourself in color or grayscale
Posters in sizes for legal paper or 11×17
If you have an idea for another publicity item you would find useful, feel free to let me know.
