I have some constructive comments.
The fliers look great. Excellent job Street Wolf! The only exception is the pictures make the forum look like it only deals with upping the performance of these cars, which is fantastic! In my area we have a few W-Bodies that are used for race applications, but majority of Grand Prix owners, particularly the older generation, don't have interest in putting performance modifications on their car. I've seen a few people on the site itself that only care about their general maintenance, and maybe getting better fuel mileage out of their car.
I propose you maybe put a sentence going across the bottom of the 3 pictures that says something like "Info on everything from general maintenance to high end performance is discussed"
Also I see a lot of W-Bodies period, so maybe another quote that says something like "All makes and models of cars are encouraged to join!"
Finally, how about making a second template with a bigger design to fit on a bigger peice of paper. Maybe have more pictures spread around, like some older generation W-Bodies. Also maybe having a list of the benefits to joining the forum such as...
1. It's 100% free to join! (I'd never pay for a forum if I did find one that charged... still)
2. Ask questions about your car and expect many replies from enthusiasts wanting to help!
3. Administrators do a great job of keeping the environment friendly and resourceful!
4. Very benefitial advice for increasing the performance of your vehicle, whether it be more power, better handling, better braking, and even better fuel mileage tips.
etc.....
Then maybe a few examples
I'll use one that I'm working on now...
"Members on the forum have been converting their vehicles to run on e85 fuel. Much discussion, advice, and even pictures walk you through and show you what it takes to do the conversion and get away from high gas prices!"
Off subject: ^^^ when I start the e85 conversion I do plan on taking pictures for a visual walkthrough of the swap, along with writing up my experience during and after the swap.
If I meet someone and talk with them I'd tell them about the site and hand them a big flier. If it's just a car sitting in the parking lot I'd put the small one under their window wiper or something.
I hope this was helpful and I'm in no way critisizing the work you've done already Street Wolf. What you have now looks amazing! Excellent job!
