Well i figured since this forum uses the frihost dollars maybe you could use them like a store.. like.. to buy Extra MB of storage on your account. It would get people posting i think. Like for 100 frihost $ you can buy 10MB? Just a thought.
It has been suggested many times and I believe it will be added in near future.
As Sunny said this has been suggested many many times before, but there are a few many reasons why it is not going to be put in place:
1. Spamming (Fih$ by posts will increase posts .: increase spam)
2. Bondings wants everyone to have exactly the same hosting spec.
