It is very easy. Forum is basing not on the paying for something, but giving from yourselve. For exaple: if you anwser to some people questions you earn NullCash. If you create new topic and putting some module or theme or software which is not avaiable on this forum you earn NullCash for this. And by this you can use other people modules and themes because you earned this NullCash by your time and you software/themes etc. Now it is no possibility to buy NullCash. And remember that spaming for getting NullCash is forbidded and you can get banned out of forum.
