As Thinfourth already said...and your car (if you have one - it doesn't have to be an Elise!
I always liked the line " welcome to scottish elises you don't need to own an elise or be scottish"
We don't want it to become an ad fest. I'm not saying don't do it, and in most cases on here, it'll be OTHER people promoting your product which is great, I think we don't want people signing up simply to advertise themselves...?Personal testimonials and recommendations to try a particular supplier or product etc are acceptable in the course of general on-topic posting. Spamming topics with recommendations for products/services for the posters personal profit are not allowed
Greg's suggestion seems perfect too

NLC - I like the NLC thing. It means that, whilst there is some drivel in general chat (which there always is...) it is still general chat.
I have/do post on various forums that split into 'anything goes/fun and games' and 'related content' type subforums and it doesn't work too well.
Personally, i'd ignore the non-related stuff, and miss out on a bunch of decent conversations, simply to avoid the garbage. NLC lets you know what the content isn't about, and often the crap topics fade away off the bottom of the page anyway...
