Many forum users have invested a lot of time into the forum, so why not turn this time-equity into tradeable commodities? You can now trade forum NFTs (fNFTs):
https://bitcointalk.org/fnft.php

We are using a state-of-the-art blockless-blockchain-database to avoid any annoying fees or wait times. Everything is done using a convenient Web interface. We have also automatically detected how many bitcoins you have to trade with, so no need to worry about deposits or withdrawals.

Features:
 - You automatically get the full set of fNFTs in your own series, from lowest rarity (I) to highest rarity (up to XI). The number of fNFTs in your series depends on your activity. Note that more than one copy of a particular fNFT can exist in the system: they're like trading cards, with rarities.
 - You can get a random fNFT for 50 BTC. A great deal, no? How could you not make money long-term?
 - You can list any of your fNFTs for sale.
 - You can buy fNFTs listed for sale by others.
