And with todays laws, it wouldn't take much to get a court order to get information from a forum admin. I'd hate to be slapped with trespassing, damage to private property etc.

That'* why we have business cards. They can be left on the car in a non-permanent manner that won't damage the finish/wiper/door handle etc.

Can't go for trespassing if they did it in a parking lot but you can bet I'd be getting ya on vandalism.

Yea I've left quite a few cards on Bonnes so far

I think I would be just a little upset if I found a sticker on my car not put there by me.

A forum card is one thing because it'* not permanent. If I found a sticker on my car, I would be, well, to put it lightly, pissed off. I'm Yutzy on what I would do
