Wow so many suggestions. Reminds me of myself always coming up with new ideas for projects or this forum. I am sure they will be deliberated on in the next DNF brainstorm effort -=DCG=- brings up in the company meeting on Friday morning headed by the notorious impactadmin.
Regarding your suggestions. DNF$ are not worthless forum currency like other forums that is given out as water. As far as I've seen, I don't think any forum gives out F$ for PM's. You are awarded F$ for your participation in the forum to help the community grow. DNF$ can be bought and sold for real money. If you are looking for more DNF$, I would suggest visiting the DNF Bank where you can purchase more DNF$ at a rate of $0.01 per 1 DNF$.
