Like I said, I have respect for all the enthusiastic efforts done by some community members. Nevertheless, they lack the skills and funds, leading to very poor results.
Maybe you haven't been around Gulden long enough to know that many have tried before, including rather wealthy and skilled people. They have all been classed away by Rijk.
Let's be honest, who in their right mind would spend a decent amount of money (€ 50k+) out of their own pocket to pay for marketing, knowing they will only get resistance from the dev's? And why should anyone have to pay for that at their own expense, while Rijk is sitting on a fund of multiple millions donated by the very community that is begging for good marketing for years now?
Trouble is, Rijk can say "if you want marketing, go do it yourself", but the fact remains, he will always try to keep the funds to himself and never spend it on something he hates (like marketing).
Only then, when the funds are released to the rightful owners (the community that provided for it), will Gulden flourish. As long as it remains held hostage by the narcist dictator, Gulden will stay hidden in obsolescence.
