As the site continues to gain new members, I know that for me, it would be nice to have a little more separation between subjects to make it a little easier to find things and/or post questions/suggestions/thoughts that are more on target the the subject forum.
One I'd like to suggest is something along the lines of "Car Care/Aftermarket" for discussions on waxes, interior care, tire/wheel cleaning, interior mods, etc. I don't know if others would be interested but I though I'd throw the idea out there for discussion.
Prior to buying a Boxster (pick it up today, yeaaaaaayyyyy), I was a Miata owner and that community has a great resource in Miata.net with a large forum
http://forum.miata.net/vb/ . Since they have many more members it is easier to get by with as many sub-forums as they have.
