It's increasing the amount of registerations and the amount of people posting and keeping this forum active also I'm hoping to get 10 Bitcoin to donate to the forum 
I would argue that it's killing the forum... Increasing registrations and people posting isn't always a good thing, it's quite hard to find useful information here now. The only reason I come to the forum is to moderate really, I hardly spend any time at all browsing because it is way too hard to find anything of importance.
Also, why do you want to donate to the forum? More money is definitely not needed, you should look how current funds have been handled, and it'll take a long time (if even possible) to earn 10 BTC from paid signature advertising.
I would love the abilty to change my name and have donator as personal text because that looks badass. What do you mean people have donated and have not recieved their rank? Where can I find this? theymos recently paid 1 million for a new forum which would have a impact on the remaining donation amount and the up keep and security of that said software would cost a lot more which I would expect him wanting more donations soon?
