Hey Oscar, is there any chance of the site getting a mini IQ test for when you sign up? That way, you don't end up with all of these people posting ten posts that just say HI so that they can download tracks.(Or at least, it's less likely)
If people have the ability to download and ride tracks, they should be able to pass an IQ test haha. I saw make the new members look at the picture of Gazag in the speedo for a good amount of time, and if the last the entire duration, they are in.
Or a trigonometric integral where substitution is required nah, at 13 kids still struggle to understand variables not calculus. Rather ask a simple question like what value earth's gravitational acceleration is in m/s squared...
7th grade (13) was Pre-Algebra for me, so introduction to variables and stuff. Maybe something simple like "If |5x| = 25, what is the value of x?" Then people freaked out by the variable or absolute value brackets are confused and fail, but people who say 5, -5 or both will pass. This would permit most people 13 and older to the site, and a few non-stupid younger kids.
