My original statement regarding the lack of Mods only really pertains to those posts by people who add nothing to a thread. IE: spammers, automated bots, people who add nothing prevalent in efforts to sell products that has absolutely nothing to do with karting.
I think this is still a great community, its not necessary that people take a quiz or be ridiculed on each post they first make as long as it is a sincere mistake. Keep in mind that a great deal of people on the internet who will be attracted to this site are not going to be tech savvy, we have a large number of new users who don't know how to upload pictures or describe their problem much less navigate through a complex process prior to being able to post at all.
We don't need people deleting posts, we need people directing them. A quiz will send the wrong message.
The masses who really are the main karting audience typically do not enjoy tests, if you tell them they need to take a test to enjoy the privilege of posting on an online forum, odds are over half of them would just give up. Honestly, I like tests, but if you were to have that here in place when I was searching around there is a chance I would have felt it was not worth my time.
Basically, the community will lead people in the right direction as long as they can abstain from going on a witch hunt. I have no inclination to be a mod here(given the lack of necessity), I've done it on 3 separate forums over the years and it gets petty after a while.
