That sounds like a great thing...I was thinking an online mag of some sorts. I would think though about incorporating into a monthly news letter.
As for writers, one or two just won't cut it. You should look at having the country broken down into regions with 5 voluteer writers or so from each. Not all submitted articles should be published at once though. You should save them for slower months like now. I would be willing to submit an article from time to time, but can't commit to anything on a regular basis. Like many members, I've got a full time job, a growing family and numerous other commitments that take my time.
You may also look at getting writers from some of the different clubs or enthusiast groups. That way you can have a lot of diversity instead of a lot of stuff from say the Mustang crowd and the Camero crowd. I'm not trying to point anyone out, just using them as an example, because they are popular cars.
Basically some freelance writers can submit articles is what I'd suggest. Not sure what motortopia's vision is for the future regarding something like this. Just some ideas to add to the pot.
