Now, I know most users will flame me for suggesting this, but... here goes:

I think that the points system, as it is now, is kinda deficient. You earn too many points too easily. This way the balance between the available points and available services will be destroyed (a.k.a. INFLATION). I suggest either lowering the ammount pf points one can earn by posting/starting threads, or lowering the value of points.

As an example, I now have 15 posts and around 86 points. At the rate of .03$/point, I have 2.6 US$.

The worst scenario would be when users reach 2000 or so points (equivalent to 10$) and ask to sell their points. You cna figure what the result will be
